I got the same problem w LO when he was this age (wk12)
He has just back to long feeding time this wk (wk 22).
I think because they more alert w the surrounding cause he was easy to drop of breast even just a cough from....neighbor...
My LO had wet nappies as well but not heavy & he still gained weight at that time (0.5kg/wk

*sad*).
However, after that period he just back to normal & I can feel him getting bigger straight away. I think this wk he gains 500gr at least

Just try to ...encourage LO taking more (to reassure urself

. Hehe) & I think that is OK for overfeed w BF
