DS is 2 weeks old. He is already 1lb over his birthweight & has plenty of wet/dirty nappies. Every feed I'll offer him one breast which he'll drink from from around 10 mins & then come off. Everything I've read says to then offer the second breast, but if I do this he seems to really struggle with the faster flow of a full breast & ends up gulping, spluttering & crying. Can I therefore assume he gets enough from one breast, and not offer a second?
