My LO is 9 weeks old and I will be returning to work in 2 weeks, she is EBF and I'm trying to introduce the bottle. How often do I bottle feed vs BF? I don't want to confuse her. LO has refused the bottle for the last 4 days we have tried a couple of times a days and final she took it tonight. I'm now not sure on how to balance things EBF, bottle and pumping. Please help.
