Re: Switch to formula
Good advice from the PPs. Go slow and you should be fine.
I know you're here for advice on weaning, but I'd feel remiss if I didn't suggest a couple of alternative strategies that might enable you to breastfeed longer. First, you could take your honeymoon just a little later. You've already upended the traditional sequencing of marriage-then honeymoon-then baby, so why not upend it just a little more and push the honeymoon back a month or so? Second, you could just put her on formula for the duration of your honeymoon, pumping or expressing only if you felt uncomfortably full. By 11.5 months, a lot of babies are already eating a lot of solids and not nursing that much, so leaking/fullness might not be much of a problem. If you did it this way, it would probably be easier to pick up with nursing when you came back- and toddler nursing is really useful as a parenting tool and often a lot of fun.
No pressure, of course!!!
