Bobby always need me to "start" his, which means I take the first bite. That first bite is hard for him to get his little teeth into. Daniel has recently been having me "start" his, too. They like having things the same. Then, they are ready for consumption.
I dont cook apples often because I dont need to. They are fine just as they are. Peeling and cooking reduces the nutritional content as well as costing extra money in ingredients and electricity. It takes extra work on my part. That is a lose-lose all around.
My kids dont always finish their apples, though. Amy Dacyczyn recommends making individual microwave apple crisps with these reject apples. Putting sugar and unsoaked grains onto a perfectly good apple seems like a bad idea to me.
When I find a half eaten apple, I chop it up, with the peel on, and throw it into a bag in the freezer.
