Re: I'm not ready to wean he isn't either
with the PP. 2 nights away probably wouldn't hasten weaning, though there is always a chance that it would. If you don't want to take that chance, or if you simply don't feel ready for your child to be separated from you for that long, there is no reason why you need to allow anyone else to push you into it.
Who is the "family pressure" coming from? Grandma and grandpa? Or is it coming from within your marriage, perhaps your husband saying that if you would let baby go with granny and grandpa, you could have a bit of time to focus on being a couple, rather than on being mommy/daddy? If it's coming from grandma and grandpa, I would ignore it. They had their chance to raise their own kids, and they don't get to interfere in your children's child-raising experience just because they want to play mommy and daddy again. If it's coming from your husband, then maybe some outings a little closer to home are the answer, rather than a long separation. You can sell them as practice runs for the longer trip.
