That's ridiculous. You are just following doctor's orders, and every baby is different. Can you get a different nutritionist? Do you have to visit a nutritionist at all? I can't see what harm it would do to a baby anyway to give him a little cereal earlier than 4 months. If it makes you feel any better, we starting putting a little bit of cereal in Ty's nighttime bottle earlier than 4 months. It made such a difference, he wasn't waking up nearly as much to eat. You are a wonderful mother, don't let that crazy woman make you think any different.
