Good Morning! We have four little darlings under 6
and have taken them all as babies...my advice could be about 10 pages long...but here it is in a nutshell
*have an infant carrier, we favor wraps over bjorns nice break from the stroller and give you more freedom and hands for your other kids, like in FL in MK where you can park your stroller and walk to the attractions...
*nurse on dark rides or dark shows, it is cool and dark so others have no clue and you don't have to stop later (I have nursed through SW, HM, Pirates, SSE, GMR, TTBAB, Mupptes, etc NEVER once did anyone look twice I am very sentive about nursing in public)
*take the Medla steam bags to really CLEAN your cups, bottle, pump parts, pacifers etc...I would take them to the hotel microwave with water for 2mins, each bag can be used 20x, washing in the hotel sink was not enought for me to think they were really clean
*have a fan in the stroller, espically for naps...ours is works on batteries and was 6.00 at Target we attached it with velcro strips...
*have a rain cover, I know people say the ponchos work but they don't when the wind is blowing. Our kids were always high and dry, in fact I had a man offer me 50.00 for mine in EPCOT b/c his kids were SOAKED and crying and more rain was coming for the next day.
*have an extra onise in your diaper bag, if the baby had a really yucky diaper, burps up 1/2 a bottle or is too hot and sweaty a onsie will work as a costume change and not take up space.
*have a towel in your stroller, we put ours down under the baby, because our stroller fabric seemed like it held heat and was not soft...then we could use it to sit on for parades or to dry our stroller or oursleves off from rain, Splash or Kali
*Use the baby care centers, they ROCK and are a nice break, our 3rd a girl was just in foul mood at EPCOT and we were about to leave for the day when we stoped in...I rocked her in a quite room while my other kids played with a lego table with my husband. She calmed down and we stay the rest of the evening to see Illmunations. It was a nice break for the family.
Enjoy and take pictures! I say take them as much as you can before you have to pay
