Ok got it! I haven't done child switch too much, so not entirely sure. Here would be my picks for FPs in each park, none should really be too surprising. I put the WDW exclusives/or ones that are different enough up front.
My strategy is to stack your 3 dailies as early as possible right up against one another so that you get access to your other FPs early enough. Even if you have just one left that isn't active until the evening, you will be tied up the rest of the day without access to FPs. Put the big ones up front as those are harder to come by later in the day, leaving you with the easier ones later (i.e. your Pirates, Haunted Mansion type attractions.)
Note that all parks except for MK have tiered FPs which means you'll be unable to stack 3 of these at any given time. So you'll be forced to throw in others not on this list by default.
MK: 7 Dwarfs, Splash Mountain, Space Mountain, , Big Thunder, Peter Pan
Epcot: Test Track (Single Rider), Frozen, Mission Space (go for Orange, the intense one!!!), Illuminations
AK: FOP, Expedition Everest (Single Rider), Kilimanjaro Safaris, River Journey, Festival of the Lion King
DHS: TOT, Rock N' Roller Coaster, Midway Mania
