Last night Luke woke up around 4:15 in the morning. He wasn't super fussy, but he was loud enough to keep me awake. So, I went to check on him and changed his diaper. Well, as soon as I put him back in his crib and walked away he started to really fuss. So, we decided he probably needed a bottle. Daddy went down to make a bottle and Luke started to cry, so I went in to calm him down until his bottle was ready. I gave him the bottle and after that I didn't hear him again until about 8:30. While I fed him his bottle I realized that during the day yesterday, he only had 4 feedings when he usually has 5. I guess in order for him to sleep through the night, he needs 5 feedings during the day.
