Despite what you think, your children are NOT retarded. They will tell you when they are hungry. You don't need to argue with them or force it on them.
If your kids don't ever get hungry (that dude the daughter a few pages back), they should see a doctor. Might be a hormone problem. Maybe hyperthyroidism or something. I seem to know a lot of people with thyroid problems.
You're wrong. I never made the claim that I believe my kids are retarded, and you are wrong in creating that assumption regarding how I view my children. They most certainly are not retarded. What they are, however, is very active. My kids get hungry, but that doesn't mean they're willing to stop what they're doing to come tell me. In fact, if they get over hungry or over tired they turn into little monsters. So, it's my job as a parent to make sure they eat and don't get to skinny.
I think the key difference here is my kids have high metabolisms are must eat regularly and often. Otherwise, the doctor starts mentioning them not gaining weight, and in turn gets us worried. Yea, they've done all the tests. Doctors come back negative results on everything, just tell us: "You've got very active boys, feed them calories."
The people who don't have to worry about feeding their kids, well...make sure you teach them good eating habits or they'll join the obese masses.
