I started back at work this week, 3 days (Mon, Thurs and Sat)

MIL gave bottles during the day and now he won't feed from me. Bed time and during the night feeds are fine, will have 5am feed but anything after that he won't. Only from a bottle I thought he would get over it, but he has been like that on all my days off. We have given bottle before and it didn't affect breastfeeding.

Any advice on what to do to get him to nurse? I tried the "if he is hungry enough he will feed" trick but he gets more frustrated (tried for 20mins), then after a bottle he is fine.
