My little chap is 10 weeks old and I'd like to express into a bottle. I tried at 7 weeks and while he was a bit confused he did manage to latch on. After that there was a bit of a break because of Xmas and we were staying with my parents. Last week he was decidedly less keen. Any tips? I love him dearly but don't think it would be a good idea to be the only being that can feed him.
