Hi Donald,
Welcome to the Disney Parks Moms Panel and thank you for your question!
First things first: don't worry!! We visited Walt Disney World Resort with our little guy when he was 5 1/2 months old, and I didn't find that we had to worry about running out of "baby gear" for him, even without the little bit of "pre-planning" we did.
There are two services that we've used in the past for delivery of baby/toddler gear: Babies Travel Lite and Garden Grocer. Both have the essentials (diapers, wipes, formula etc.) but I found that Babies Travel Lite had a better selection of brands and miscellaneous items like bath toys. You can place your order with either service at any time - just specify your check-in date at
Disney's Grand Floridian Resort & Spa and they'll have your items delivered in time for your vacation. I've also heard of some Guests having good luck using Amazon. A quick Google search will help you figure out which option is best for your family.
The
Baby Care Centers also stock some basic baby items. I can remember two occasions on which I was particularly grateful that they sold diapers and sunscreen as I hadn't put them into the diaper bag that morning! Your resort's gift shop,
Sandy Cove Gifts and Sundries, will also sell limited quantities of essential baby items. That being said, these locations only sell a limited number of brands and their prices are higher than what you would pay if you ordered these items online or purchased them in a conventional store.
Have a Magical Day,
Lynne
