This will be our first trip with our newest baby! The other two, we first took at around 18 months. We are currently deciding between spring and fall for the trip, he will be a year in August and I imagine will be walking then. I can't decide whether it is better to go in spring, before he can get around (away) on his own...or to wait until he CAN walk so we don't have to hold him all the time. We will have a stroller for him, and probably a back carrier. Am having baby amnesia, but I THINK the other two were more difficult to handle after they started walking...although that Disney commercial shows the Mom who doesn't want to go until the baby can walk (haha), I wonder if there is something to that! Any opinions? Thanks in advance!
