we have a trip booked for this upcoming November, we booked our flight and resort already, we found out yesterday that we're expecting and my due date is about 5 days before we're supposed to be leaving, we were able to switch our resort dates to mid December, our plane tickets are non refundable so we had no other choice but to push it back to a later date, and pay a penalty fee of changing the flight, baby will be a month old or so, I'm leaning towards leaving him/her with my mom during the trip, but I feel so guilty knowing I'll leave a tiny baby behind
As long as everything goes as planned I think it's totally doable to take the baby, however if your mom's on board and you feel she's capable then I wouldn't feel bad for leaving the baby either - it'd probably be a nice break for everyone to be baby-free for a little bit. As far as you being ready or not...we took my 3rd at 7 weeks and I can remember at 2.5 weeks after i had her feeling like I could definitely do Disney at that time, so as long as no issues come up I wouldn't worry about that - and it's not like this is your first, so you know what you're in gor.
