We went last august with our then 7 month old son and it was really hot at the MK = high 90s... After his first haircut (which was supercute with the Mickey ears they give!) I laid out a route through all the airconditioned shops to the baby care center. We must have spent hours there in the baby care center....back and forth between rides and for naps. Only did a few rides but we hadn't planned on really doing many as we were expecting it to be busy (which it was) and so we did the Pooh ride, Its a small world (where I nursed for a short while in my sling!) and Philarmagic (alittle loud I think for the baby but he didn't seem too bothered by it.) I made my own solarveil sling and carried him and also held a large umbrella to shield from the sun (also cooled us somewhat) and also had two clipfans for the stroller and a pocket mister which I sprayed on all of us every so often. Best part of the day was lunch at Crystal Palace. Would I do it again??? Probably not even though we got some great photos...the heat really was dreadful and we were happier just spending time at the pool the rest of the week and venturing out at night to nice restaurants to catch some Disney magic! Plus the crowds were insane!
