thanks both of you. he is on solids, we started cereal at 4 months as we had to cut down his intake, he was eating over 50 oz a day. he was doing great when we started the cereal and his intake went to 35-40, it was just the last 2 weeks he was going from 6oz to 4oz and waking every 3 hrs at night to eat and he was also going throgh a growth spurt at that time as well. SO i though it was time to upgrade. just in that day he went to eating 6oz again and draining it so quickly i didn't know if he was too fast, so i upped it to 7oz and he is draining that too. do you know when they go up to 8 oz bottles? i guess if his tummy will hold it, i guess, hey. i was hoping if he can take 8oz then h can go to 4 hrs between feeds with solids after his bottle as always.
