Hello Kirsty and welcome to the Disney Parks Moms Panel where it's always a joy for me to assist another family from the United Kingdom with their jolly holiday plans to visit Walt Disney World Resort.
You've already made such a great choice by opting to stay
Disney's All-Star Music Resort next summer and I just know your darling little Mouseketeer is going to love all the larger than life theming and should especially enjoy the amazingly splashtastic
Pools!
I'm happy to share that Disney's All-Star Music Resort does indeed benefit from a great shop named
Maestro Mickey's which should stock a small selection of grocery sundries and baby foods to purchase, however if your little boy is used to a particular brand of infant formula if may be prudent to bring a supply with you from home.
Another idea could be to utilise an online delivery service such as
GardenGrocer.com where Guests can pre-order grocery and sundry items to be delivered to
Bell Services near the
Lobby Concierge at their Disney Resort hotel; I have great personal experience of ordering items for my own family such as bottled water, snacks and so on and it truly works like a dream!
It may also be helpful to know each Disney Theme Parks has it's own
Baby Care Centre where Guests can also purchase baby sundries, formula and food items and nurse, feed or change their little ones.
Have a great Disney day.
