ds is doing great with bf and gained roughly a pound a week. th last few days he seems to be more hungry on a night and tonight i've got to the point where there is nothing left for him! he is constantly searching and therefor won't settle. I have a small amount frozen breat milk but havn't gone down this road of bottles etc yet - should i try? if this carries on don't think i'd have enought to express - should i consider formula to top up? bit clueless as 1st timer.
