Hello! I have a 9 week old DS (& 3 year old DD) I only bf DD for 8 weeks & due to problems with PND and chest infection went into formula so I feel totally clueless about what to expect with bf? He's only just started doing a 5 hour stretch at night & that's not consistent - v random. And the rest of the time its 2-3 hours. He seems very happy and content but I have these nagging doubts I'm doing something wrong as 2 friends with babies same age are doing 7 hours at night! X
