Hi,
My baby is 4 1/2 months. He's been breast feed until now, and I wish to continue but want to be able to give him bottles on certain days when I need to work. He initially from 2 months, took the odd bottle, so we didn't think there was a problem. Now he rejects most bottles, getting quite upset when I try. I've tried expressed milk as well as formula. He is teething also. We've been using Avent bottles. Help!!!
