If/when you do have a kid, I highly suggest going as close to, without going over, their 3rd birthday as possible for a first trip. Assuming they're not afraid of characters and have no problem napping in strollers, it's a great time. Plus they're completely free (especially when you hit as many character meals as possible).I guess I see families who are just pushing the whole group the entire day, either to experience everything possible or to get all the photo ops to satisfy Facebook/ Instagram mom, to the detriment of everyone. And agreed, you aren’t going to post pics of the kids tantrum or “another 45 minutes in line for Frozen! #killme”. But I guess maybe the whole myth perpetrated on social media by some people makes the “magical experience”many people expect when they go simply impossible.
And I get it- the window of time to take your kids to WDW and have a memorable experience seems large, but they’ll be grown and gone before you know it. If it were me, I’d probably take the kids a year or so early myself, but I’d just prefer to be as sure as possible that our time and $$ were fairly well spent. When I see things like in my original post (kid melting down within 2 minutes of park entry) or I see dads at the resort practically mainlining alcohol & cigarettes at the end of the day, I guess it makes me think people should really consider if the kids are ready. And sometimes when the answer is clearly “no” then those tend to be the people I vent about on related threads about the family barricading the FP entrance because they don’t understand it, or generally inconveniencing everyone in their path the entire day, when the kids would have been much happier at the resort pool.
