Trying to figure out what we should do for full day Kindergarten. I have an old iPhone 4S that I could pair and send with my son... but he's 5 years old! Is this what others do? Do I have the teacher keep the phone/receiver on her desk while they're in class then he carries it with him in a little bag to PE/Library/Recess/Cafeteria etc.? I love the idea of being able to see his trend graph on my phone during the school day. Never in a million years did we think we'd give our 5 year old a smart phone.
