Hi Ladies! My LO is 4months old and taking 3 1/3 oz bottles every 2 1/2 hours when im at work.  Dr. Suggested we change to nipple size 2 and give her 4 1/2 - 5oz bottles every 4hours.  We tried today and she still only ate 3 1/2oz and fell asleep.  Any suggestions as to how i can get her to eat more?  Does she just have to get used to it gradually? I express milk and dont want to waste away that extra oz that she doesnt eat..😏Any advice is appreciated.
