I guess I'll be part of the "problem" and keep this thread off topic but I just have to respond...
When parents take babies or young children to WDW it's because they want to. I know it's hard for some of you to understand but parents still like to leave the house even after they have children. Just like you'd take your children to the playground, the zoo, a toy store, grandma's house, etc. Some of us like taking our children to Disney World because *gasp* we enjoy it! The children will remember it no more than the last trip to the playground but that doesn't mean it wasn't enjoyable or memorable for the parents. (Oh, and by the way there's some fascinating research on babies and young children's memory, while they don't remember specific events, what happens during childhood leads to memories that help develop their contentment level, confidence, etc.) Having a baby doesn't mean you should be confined to the house or have to change your travel plans. Babies and young children are part of the family and get to be part of what the family does (whether they remember it or not). If folks want to tour Europe, snorkel in Austraila, skiing trip to the mountains, or a vacation at Disney World, babies can travel to all those places. Vacationing is more about spending time together not necessarily what you see and do. Sure you get to see and do different things (that's what makes a vacation fun) but it's the people you're spending it with that make a family vacation special. I think it's just plain crazy to suggest that parents leave the child home (with grandma) or not go because they have babies!?! If folks want to leave their baby home, fine - that's what works for them. And I'm not suggesting parents should never get away without the kids (it's healthy and good for a relationship to do so every now and then). But if they want their child with then on vacation than why the heck not?
