I had a big baby (nearly 10lbs) and I am breastfeeding him. It's all going well, and he is 4 weeks old and weighs over 12lbs (could even be more but have not had him weighed this week). The health visitor told me that breastfeeding won't be enough for him and I should give him at least one formula feed a day (at 6pm). At the moment I have ignored her advice, as he settles well, has lots of poos/wet nappies and is gaining weight. BUT......has anyone else had a big baby and only breastfed? Should I be supplementing my feeds with formula? Any advice?
