Quoting Bailee & Delilah:" I had to ask because she drinks 4oz but she spits up most of it. I think she might have acid reflux and she goes to the Dr on Thursday so inns talk to her Dr."
in the first month my son always wanted 4 oz, but if i gave him the full 4 at one time he would spit it up or get sick. so i started doing 2 oz every 20 mins. it stopped him from spitting up and getting sick and now at almost 2 months he is able to take the full 4 oz along with another 2 shortly after... but every baby is different so it is better to ask the dr :-)
