About not being able to take care of them, what's wrong with expressed milk? I would think that would be more comforting to them too especially while mum isn't there, but her milk is! Luckily my family have been pretty good, my mum fed me until 12 months so she's pretty good. Now having my second they don't bat an eyelid anyway as they know what to expect from me I guess. I think so much of it has to do with how they were fed. It's what they know and are used to, so it must be right
