Hi! Formula feeding with my dd has been going swimmingly since we started in late December. But the past two days or so she hasn't wanted very much and she hasn't been eating as fast as normal either. She usually will eat 8-12 oz at every feeding (4 per day) but the past two days she's only wanted 4-6oz. Is this normal? Will she go back to wanting more? She's very active and very very happy, so I don't think she's sick. She has had solids and I try to give them to her consistently, but she doesn't want them and barely eats them. She has no teeth yet. Thanks for your help!
