I have one of these back zip hoodies and they are the best things ever invented for keeping a jacket or sweater on a nimble toddler who has figured out how to undo every piece of clothing. This also has the advantage of being reversible so you get an additional option for matching more from the wardrobe. It is 100% alpaca, the softest thing in the world, so you know your precious is not only warm but comfortable!! I know we are getting out of the colder months but unless you are right on the equator, you still need a cover up for summer nights especially since there are more outdoor nighttime activities then. This hoodie comes in a huge variety of colors for boys and girls. Available at Ouef NYC, $116 for Baby (6M/12M) and $120 for Toddler sizes and up.
