Thanks again. Re the duration of fussiness, what I meant was whether LO would settle later that evening if I didn't bring things to a head with a bottle feed.
My comment about let down relates to the ending of the period where LO has been sucking and swallowing milk - he usually only does this for 5-10 mins before reverrting to smaller sucks (no swallowing). Swallowing resumes when i have another let down
sorry comments are short - have lo in my arms
