We took our first child to WDW when he was 10 weeks old and had a wonderful time. My suggestions:
-We were using formula, so brought individual cans/bottles which were one use amounts.
- We used a carriage bag (attached to stroller) plus
carried a backpack to bring ziploc baggies for wet/soiled clothes, a washcloth in another baggie for washing baby's face, plenty of changes of clothes.( I remember a particularyl nasty "blow out" and was glad I had all the above!!)
- Keep baby covered in lightweight clothes- no sunsuits, even if it's hot- they're too easily burned!
- don't forget a good hat
- I always carried several thin receiving blankets and some clothespins to make a sheltering canopy on the sides of the stroller for when the sun is low and slanting in. They're also good for draping across your bare skin when your'e holding baby- if it's hot- that bare skin to bare skin can mean extra heat!)
-bring an extra one or two of baby's favorite pacifier- you're bound to lose one (we did) unless it's hooked to baby.
Hope this helps and have a wonderful time!- don't forget to get a picture of Mickey or Minney holding the baby for his first trip there- they will usually motion that they want to sit down to hold the baby, but it turned out so cute, we made sure we got an identical picture 4 years later with our second son!
