Pointers? BE FLEXIBLE!! Go with the idea that you may not get everything done and that's ok. We will be there the 17th-30th with a 13yo, 12yo, 10yo, 9 yo, 7yo, 5yo, 2yo, and a 6 month old. Our 4th trip with kiddos and we were there around the same time in 2013. Nice weather and decent crowds. We've found that staying longer helps us to relax, we'll go to an ADR before the park opens then stay until we feel like heading back to the house/resort and then come back for evening shows...etc. We avoid the hottest and busiest part of the day this way and the little ones can get some naps/relaxation time. We take it easy and make sure we aren't pushing too hard.
Dark rides/shows are great for nursing or feeding the baby...my wife likes the people mover, COP, and HOP for this
We use a stroller and an ERGO carrier
