Hello!
First of all, good for you for going on a trip with your husband!! I think it will do wonders for tour marriage. My boys are 3 and 20 mos and I haven't left them overnight, except when u was in the hospital having my youngest.
As far as her only wanting the bottle once you get home, you should be fine. If she were 6 weeks, I'd be more concerned. But she's a booby baby and I cant imagine that would change on such a short period of time. If she had any issues when u arrive home, be patient with her. When my second son was born, he was jaundiced for 6 weeks. I am a VERY pro-BF'ing mommy. So nursing him was going to happen. He also spent his first 5 days in the NICU. They wouldn't letme nurse him until they got his breathing under control. I was so worried that he wasn't going to nurseb/c he got bottles. Then with the jaundice, I had to
Interupt BF'ing 3 separate times. One for 24 hrs, the next for 36 hrs, then finally for 7 days. He was under 6 weeks old and I was do worried that nursing would be difficult. But it wasn't. In fact, hes 20 mos old and hrs still nursing like a champ.
Have a great vacation!!
