My dd (5 mo, my first) is now feeding only for about 5 mins (one side only) every 2-3 hours. She used to feed for longer e.g. 10 mins, about a month ago. Currently going through some night wakings and I think she is teething (lots of swollen gums). Last time she was weighed she had put on 7 oz in 2 weeks and is just about following the same line. I wasn't worried about the gain being quite small as it is more than her gains a couple of months ago (e.g. 2 oz one week, 3 oz another). Plenty of wet nappies still and she is her cheery self. Should I put this down to the teething and/or her feeding becoming more efficient and not worry? Should I be offering the other side? thanks for any advice.
