Cheese is great! And if he is like my sons?...the juice will help him stay un-constipated! Do you ever notice when he has a little more juice than normal? his poops are more yucky and more frequent?? Apple juice is a great pooper-mover..and so letting him eat more cheese and drink more juice, balances the whole system....but if apple juice is a tummy upset? Try the white grape juice..and Juicy Juice brand is one of the healthiest, 100% juice, juices to give...between the yogurt (let him have as much of that as he wants too, as it strengthens his digestive system) and cheeses, and that should be PLENTY of calcium! How do I know? I have had the same problem w/my now 3 yr. old son, and he has grown up just as healthy as a horse, his check-ups are fantastic..and he still isn't a HUGE milk fan, but we keep doing what has worked till now and will keep on till he likes his milk...or not! No worries Momma..keep up the great work!
