Is this a good schedule for our kids? (sorry its long we are worried about their schedule being too busy)?

this sounds fine- not to busy at all. just remember to listen to your kids and see what they want to do. also, don't follow the schedule religiously- if your kid wants to do something different you should let them, such as hang out with a friend or something else like that. it seems like you really care about your kids and i admire your devotion to them and that you spend so much time with them.
