Q: I love my son and daughter-in-law, but I'm worried about their 10-month-old daughter's health. The house is piled deep with trash, there's moldy food stuck to the carpet, and dirty diapers are left lying around everywhere. My granddaughter is constrained to an infant seat to keep her from getting into these messes even though she's old enough to start crawling. Should I express my concerns over these troubling health conditions?

Jim: In most cases it's best for grandparents to keep their advice to themselves until asked. But if the situation is as unhealthy as you've described, it may be time to intervene.

So what can you do? It might be a good idea to begin by enlisting the help of another adult -- preferably someone your son likes and respects -- who can join you in advocating for your granddaughter. Raise the subject gently but as straightforwardly as possible. Help your son and his wife see that this is more than just a question of personal preferences and different "styles" of housekeeping, but that they are, in fact, endangering the health and well-being of their child. Make yourself available to help with the cleanup and to offer assistance where needed.

If they won't listen, or if you don't see significant improvements within a reasonable amount of time, you may need to contact your county's agency of Family Services. Social workers will advise you on the various options available. Among other things, it's clear that your son and daughter-in-law need practical training in the fundamentals of child-care. Mandatory counseling may also be necessary, but this is something for skilled professionals to decide.

The important thing is for you, as a grandparent, to do everything you can to enlist the support and community services necessary to raise your son's family to a higher-functioning level.

Question: I've always tended to express myself in a wry, ironic way. It's all a joke, and I don't mean any harm by it. But I'm wondering if my sarcastic style of humor might be potentially damaging to my teens. What do you think?

Greg Smalley, Vice President, Family Ministries: This can be a complicated subject, but on the whole parents need to be careful about the way they use sarcasm. This is especially important when dealing with teenagers. There are two major problems related to teens and parental sarcasm.

First, sarcasm can hurt feelings, and words uttered in a "humorous moment" can cause ongoing pain later. You don't necessarily need to place an all-out moratorium on playful sarcasm, but there should be boundaries. Give your children the right to tell you when it bothers them.

The second pitfall is more subtle. Sarcasm can mask sensitive or vulnerable feelings. Imagine a father watching his lovely 16-year-old daughter come downstairs. He might say, "Honey, you look beautiful tonight." Or, if he tends to be sarcastic, he might quip, "Man, you were such an ugly little girl! What happened?" Same underlying point, but one is obviously much more complimentary than the other.

One last point: As parents we need to remember that we reap what we sow. You may call your "style" of humor sarcastic, but when the tables are turned and it comes back at you from your teen, you'll probably call it "disrespectful." It never hurts to say what you mean and mean what you say.

After all, a teen's world is tough enough. They probably get plenty of barbs and arrows at school or on the playing field. Home should be a refuge from that kind of treatment -- a safe haven from hurt and a filling station for high-octane edification.

Q: My husband and I were married this past spring. We had a great summer and especially enjoyed doing things together during the weekend. Then came fall -- and with it college football season. I knew my husband was a fan, but now that we're married I'd prefer to be spending Saturdays doing things together that we're both interested in, rather than waiting around while he's watching his alma mater on TV. Is this situation something I should be worried about?

Jim: Couples often get married thinking the secret to marital bliss is having the exact same interests. It doesn't take long for them to discover -- like we all do -- that we're rarely just like our spouse. The good news is we don't have to be. Successful marriages aren't the result of perfect chemistry. They're built, in part, by learning how to bring our separateness together.

A local couple, Ted and Cindy, are a good example of this. They like to fish together nearly every weekend in the summer. Well, actually, Ted likes to fish. Cindy doesn't really care for it, but she loves to read and loves the Colorado outdoors. So on Saturday mornings, they drive into the Rocky Mountains, and he fly fishes while she sits on the bank and enjoys a book. They have a picnic together. They laugh. They talk. They enrich their marriage. But their deeper connection doesn't come about by forcing their individual interests onto each other. It comes from bringing their "separateness" together.

Differences can strengthen a couple's bond rather than weaken it. But it takes patience and a willingness to embrace your spouse's unique view of life. If you both will do that, you'll discover a deeper intimacy with one another than you ever thought possible.

Question: Can you suggest ways my spouse and I might use social media to encourage each other and strengthen our marriage?

Greg Smalley, Vice President, Family Ministries: Author Neil Postman says that "every technology is both a burden and a blessing; not either-or, but this-and-that." This is certainly true where online social networking is concerned. When used with wisdom and discernment, it can be an effective tool for strengthening marriages. Here are some suggestions how this idea might play out in practical terms:

-- Connectivity. Social media serve marriages best when used to maintain a healthy connection between spouses. A husband or wife on a business trip can use Facebook to share new experiences with the entire family and to give them a sense of participating in the journey. It's also a good way to hold yourself accountable by keeping family members posted on your activities and whereabouts.

-- Enhancing relationships. Some research suggests that social media, when used appropriately, can actually add intensity and immediacy to face-to-face relationships. When used as a supplement to rather than a replacement for flesh-and-blood contact with another human being, online communication can add new layers of intimacy and understanding to our interactions with those we love.

-- Walking in the light. Husbands and wives who connect with old friends via Facebook may sometimes have unprecedented opportunities to enter into the details of one another's personal histories. This can be tricky. It might become a source of tension, suspicion or jealousy if one of the partners' old high school flames decides to put in a "friend" request. But such developments can be beneficial if they have the effect of eliminating secrets and shining a light on the past.

-- Community. The healthiest marriages are those linked into a strong support group. Couples need other couples, and social media can be an effective tool for networking, discovering common interests with friends, organizing events and coordinating get-togethers.

Q: Do you think it's a good idea for husbands and wives to have regular activities apart from each other with their friends of the same sex? My husband feels a deep need to get together with his guy friends a couple of times each month, but I'd rather spend most of my time with him. I get out with some girlfriends a couple times a year, and this seems to be more than sufficient for me. What are your thoughts?

Jim: Assuming that the two of you aren't short-changing your time together as a couple, we'd suggest that it's almost always a good idea for a husband and wife to enjoy a reasonable amount of activity with their respective same-sex friends. Females need other females. Guys need guys. But this isn't necessarily the last word.

If we were sitting across the table from you and asked you to describe your marriage, what would you say? What are your expectations for the relationship? Are those expectations being fulfilled or not? Give some honest thought to the quality of your relationship. When it is just the two of you, do you enjoy each other's company, or do you find it difficult to be together? How would your spouse answer that question?

Bottom line: If you're connecting, enjoying the time you spend together, and striking a healthy balance between friend time and couple time, we don't think you have anything to worry about. A secure wife who cares about her husband's enrichment is usually happy to see him forming healthy bonds with other men of solid character. If, however, your husband is deliberately cutting you out of his life or trying to "escape" the relationship, I'd encourage you to give the situation some attention -- preferably with the assistance of a trained marriage counselor.

Q: How can I encourage my bashful preschooler to open up and break out of her shell? She's soft-spoken, reserved, and afraid of walking into a room full of people. Is there something we can do to make it easier for her to interact with others?

Greg Smalley, Vice President, Family Ministries: Every individual is different, and there are some situations in which a child's bashful behavior may turn into a cause for serious concern. But most of the time it's simply a question of temperament. In these cases, there's no need to think of it as an insurmountable problem or to treat it like one. Some kids are just born with a predisposition to be less outgoing than others.

Raising bashful boys and girls is a delicate art that requires discernment, sensitivity and balance. If you have a more assertive, confident personality than your daughter, it may be particularly difficult for you to understand her. If so, your first assignment is to get inside her head and try to see the world through her eyes.

One of the best ways to help a shy child is to show her that you love her unconditionally. Let her know that she doesn't have to perform in certain ways to be accepted by you. At those moments when she seems paralyzed by her bashfulness, respond with encouragement -- a disapproving comment or look will only make her feel even more self-conscious.

At the same time, resist the temptation to make life easier for her by shielding her from new people or situations. Coddling and reinforcing self-defeating behavior will only create additional problems in the future. If you feel like you need more guidance in this matter, you can start with our licensed staff counselors by calling 855-771-HELP (4357).
