Dear all mami,
I can understand how you all worry about it as I also suffer from it last time. It started at my bb (3 -5.5mos old). As we are the parent we are really very down & upset. We tried: dance, sing, switch on the Christmas light, hand her and walk/run when feeding. We try to force her drink some more coz she drink quite a lot when she was before 3mos. (now she is 7 mos).
I saw a lot of cases here before(they said this is called "hate milk period"), most of the BB will drink better when they are 5 mos or 6 mos.
I brought my BB to the Dr. and the Dr. give her the medicine to let her had her appetite.The Dr. asked us not to force the BB to drink as it will make her hate it more (really!). Dr. said:"eating should be something to enjoy, right? Did you think about why your BB was so angry and even throw away the bottle when she saw it?". We stop force her and let her take the medinice, after few days she really better and back to normal. I hope all your BB will drink more soon! Don't be upset, sure it will be better later, don't give up!
