I just looking for some advice/ tips from you ladies as I'm going on my best friends hen weekend soon & my baby will be 4 months old and ebf. My dh will be looking after her. I was just wondering if it will be ok for her to take some formula that weekend, I have expressed quite a bit but don't think it will be enough. Can he give her the milk i've expressed then top up with formula if need be? im not sure how much she even takes but is on the breast for 5-10 mins each feed and isnt a very big baby. Also will those 3 days away affect my supply? I'm going to pump while I'm away but will I need it to do it as often as she feeds? Thank you
