Helping baby put on weight

Louise

I had a health visitor appointment today and my 11 week old LB isn’t gaining as much as he should be! I feel so rubbish because he is constantly on my boob. I have a very fast let down and a high supply. He doesn’t have longer than a 10 minute feed. He always screams at it like he’s not getting any. They think he might be tongue tied but anything I can do before he gets that assessed?
