My LO is 7 weeks today. He is a textbook baby, I believe he had his growth sprut at the beginning of 6 weeks. Additionally, w/ the exception of a few times he is a good sleeper, sleeping 5 hours for 2 of the past 3 days. Last night, he was waking up when he would normally feed, sounding hungry. We bottle feed BM~ both times that he woke up, he only ate 1/2 his typical amount & went back to sleep. It was a struggle to keep him awake but I managed to get him to finish both bottles. This morning, my husband let me sleep in & fed the baby & had activity time. He had the same issue except he gave up w/out making him finish the bottle. I know this is only 1 night but has anyone else experienced this before? I checked his temp this morning and he is normal. Any ideas what might be going on?
