Welcome to planDisney, Naomh! I took our youngest to Walt Disney World when they were six months old, so I was delighted to see your question. First of all - I was worried about the flight, but I honestly think this is the perfect age to travel as they are so content with being with you.
The
Baby Care Centers in each of the Parks are a little calm oasis. The one in Magic Kingdom Park is particularly pretty and welcoming. If you feel like you, or your baby, need some time out, I highly recommend heading to these. The
Baby Care Centers have multiple changing stations with lots of space, and I noticed Cast Members cleaning down stations after each use. If however, you just want to quickly change your little cherub, in every bathroom I encountered, there were areas to change baby - akin to what you would typically find in public toilets. There are also companion toilets available which have changing facilities that are separate from the main bathroom areas.
A couple of other things I encountered travelling from the U.K. - the available snacks and nappies are a little different, so if you would like to keep consistency, I recommend bringing enough supplies from home. On the accessible rides, I found a baby sling super helpful for the queue and, on occasion, for the ride itself. We also found taking a break each afternoon from the Parks helpful for us all - be that back at our Disney Resort hotel or dining at a
table service restaurant.
I'm sure your little one will be mesmerised by the magical sights and sounds of Walt Disney World. If you're ready to get back into the thrill of things,
Rider Switch means that no one has to miss out. Make sure you take all the pictures and soak in the memories; I can not tell you how much my kiddos seem to grow and change between each trip.
Naomh, if there is anything else I can help with ahead of your Walt Disney World holiday, please let me know. I wish you and your little bundle of joy the most magical adventure together, Louise.
