What do I need to do right away? Her one toe is curling under making it look like there's an extra toe.
Get either a bandaid or some tape that isn't super sticky and place a square larger than the foot under the flat of foot while spreading toes out to normal position... place another square over top of foot and make sure it sticks to other piece in between the toes... this should hold the foot flat out with toes spread... carefully trim the tape around the outside and a little between the toes so it isn't a huge boot...
