Ok so my sons pediatrician said to start putting rice in all his bottles seeing as he eats 4oz every 1-2 hours. We started that yesterday and he did great! A 4oz bottle every 3-4 hours! But today he just can't seem to get full even with the rice... I don't get it. He won't sleep, he's constantly crying. I'm only giving him a bottle every 3 hours because I don't want him to over eat.
