I bumped Ava up an ounce in her feeding. Since I have done so she has been sleeping a lot during the day and night. She will sleep for a good solid 4 hrs and wake to eat and fall back into a slumber. She went from being awake 5-6 hrs a day to maybe 3-4 hrs. I keep checking her temp but no fever and she is pooing 2-3 times daily everyday. Is it normal for her to be sleeping so much since I boosted her feeding intake?
