LS, I am sure that whatever you decide will work. I would probably not wean as of the wedding day, just purely because it might be harder for her to have the double whammy of mummy and daddy away for 2 weeks AND no more bfing all in one hit. So if you are going to wean, I would probably try and do it earlier.

It's hard to know what to do, I am sad that both my boys self-weaned before 2, but that's me. Look in your heart hun, I'm sure the answer is there. And FWIW, I don't think it's selfish to wean a little earlier than age 2 if that's what you want. Your happiness is important too, and it's only a couple of months anyway. Best of luck with your decision.
