Long story short I return to work in two weeks and we've been doing a lot of dry runs with DD and my in laws. The first time we had no issues and she took the bottle fine. Since then it's gone down hill. I figured it was because MIL is bottle happy and will over feed to soothe. She did this with DD1. The times that she has been left with MIL have only been for 3 hrs tops so I haven't been too worried. Last night she straight up refused the bottle and screamed at MIL. She was offered a bottle 45 mins after I had fed her, and again at two hours. MIL thinks it was reflux and she was in pain. Part of the problem was MIL had not assembled the bottle correctly so the nipple wasnt fully sealed to the ring. When I tested this at home it made the flow very difficult so I can see DD being upset. We've tried a few different brands but I don't want to spend a small fortune trying to figure out a better bottle if she is going to reject it much like she did with a pacifier.
Our Dr warned us that she might refuse the bottle but she would either take it or wait until I get back from work. I work about 40 mins from the ILs so even some of the suggested going home to nurse or having her brought to me isn't going to work. Thoughts?

Re: Baby won't take bottle :(
Can your DH offer her the bottle more frequently? Maybe that would help get her used to it?
I am nervous she is going to reject the bottle and not eat. I am going to be away from her 10+ hours a day which is a long time to not eat.
