My LO is 16 weeks old. She used to drink ebm in bottle initially but now only wants to latch on only. she refuses milk from the bottle now and I'm back to work any advice?

It is kind of normal to me. Baby sometimes would be smart enough to create bonding time with mummy and they will also know that mummy is going back to work. Bottle feed baby is not tough but requires alot of patience and determination. My advise is to bottle feed in the day and latch exclusive at night.
