The last time we were in to the doctor she gave us a few tips to try to help with it. Hold baby upright after eating, burp her more often, give her breaks in between ounces. Nothing seems to be working. So i looked it up online to see if i can do anything else and i saw it was suggested to add some rice cereal to formula or breastmilk. Shes only going to be 4 weeks on thursday this week... is it too soon to add just a tiny bit of rice cereal to try to thicken up her breastmilk a little?
