They will allow your baby to wear a sweater (without a hood) if you request that. They will even put on your baby's sweater if they/you think your puppy is cold. If it is really cold out, they will close the outdoor area so they have to stay inside where it is warm. Remember, you have get the app so that you can watch your baby while he's there. You can view until 7p, which is bedtime, if he is spending the night. The one thing that really concerns me is that no one is there with them after 7p, until they open in the morning!! That really concerns me.
