All the daily standards: wipes, diapers, food, bibs (the disposable ones are a God-send on trips), clothes (don't forget something warm), shoes, socks, sunscreen, blanket/toy, tylenol/ibuprofen, allergy meds, portable changing pads (again, disposable ones are great), utensils/bowls, dish soap, rash cream, toiletries (you can get Johnson and Johnson travel packs), sippy cups, snacks (we took 100 calorie packs, mandarin orange cups, and nutri-grain bars). Have you checked the ultimate packing list on allears.net???
