This video show an interesting method of keeping your child's winter gear all in one location that makes for each retrieval when the moment for departure arrives.
My daughter loves to wear a fleece coat under her main heavier coat also as we live in such a cold climate. Earlier this week it was actually -10 F outside! Around our place it is extremely important that we keep our gear together so that when we need to move outside we aren't wandering around "looking" for stuff.
Long sleeves on mittens make for a more secure fit for your toddler.
Mitten keepers help keep your toddlers mittens attached to their coat, making finding mittens a much easier task when you are getting ready to go outdoors.
