DS is in a toddler bed and because he is a restless sleeper his blanket is always on the floor. It hasn't been too much of a problem because of warm nights but the cool nights are starting and I don't want to have to keep getting up to cover him all night. In winter he'll be having a blanket and a quilt. What tricks do you use to keep the covers on your kids? I have seen some clips that are suppose to work but not sure.
