I take it dad isn't the full time caregiver? Caring for kids that are too young to say "Dad, make me lunch!" can be hard because kids eat less, but more frequently than adults and when the grown up doesn't feel hungry, it's hard to remember that the kids still might! If you're going out and know that the kids will need to eat while you're gone, try making I foolproof for him by making up a snack tray or putting all the fixings for the meal in one place in the fridge so he doesn't have to search around or even decide what to make. Leave a post it note with the snack and the time it should be given and then, if you can, make a quick phone call and remind him that it's snack time. "Hi Honey! How are you? Are the kids having fun today? I know you'd have your hands full so I made some snacks ahead of time for you. I left you some cut up carrots and dip in the fridge, they might like to eat that now, just set it on the table and let them serve themselves." Also, when you are home, try dropping a few hints around him as if you are just realizing things yourself, so that he learns what the kids' usual hunger cues are. "Gee, Sam sure is whiney today! Has he had a snack since lunch? Oh, he's probably hungry!! Yup, I fed him and that fixed it!" Even if he never gets good at sticking to the usual schedule, dads are fairly trainable and kids are flexible. He will eventually learn to recognize when the kid are hungry and feed them before they riot. What you want to avoid is giving him a lecture on how to be a dad or how to handle the kids. That's a sure way to have a dad that doesn't want to be involved because he feels like he's being scolded when he tries. Dads do things differently and they often stumble along at first but they eventually find their stride and when they do, it makes for a much stronger bond!
