I agree -- just because your 2-year-old won't remember the look on their face the first time they saw Mickey, that doesn't mean YOU won't, and that it won't be a memory you treasure forever! Even if the kids don't remember their earliest Disney trip, the parents certainly will, and if taking their babies and/or toddlers to Disney gives them joy, then why not? (Granted, DH and I waited until our kids were old enough to be potty-trained and capable of going stroller-free to take them to WDW, but that was because making the trip was going to be a financial sacrifice, so we wanted to wait until the entire family could get maximum enjoyment out of it. If we'd had the means to do so, I'm sure we'd have gone earlier.)
