Hi - as a new mam (ds 5wks) I'm currently amazed by my boy and breasts! DS has taken wonderfully to bf and is a v efficient feeder, with excellent weight gain. Only possible grumble is that he feeds all the time, not bad during the night - generally goes 3-4 hours, but during the day he want it all the time.Have only used avent shells to collect milk on 1 while feeding on other so far - had an ice cube tray full and tried him with few ounces tonight and he loved it. Just want some tips on expressing, storing, defrosting, taking bottles out (what temp and how heat? - can't use microwave)? I know I sound clueless - have read up, but just wanted your tips - find mn much more straightforward!
