What do I do when my sugar gliders keep biting me?

We jus adopted a pair of sugar gliders a few days ago(Coco our boy,Chanel our girl) are both quiet happy little gliders.they eat enough and have a great diet.plenty of water n tremendous amount of play time.They even have a wheel n toys to play.But seems like whenever Chanel gets close to my wrist n fingers,she bites.shes three months old.Coco doesnt bite as much but he does nip when im hand feedin him and bites only when i try to hold him.hes fourteen months.Could it mean they wernt handled much? or do i wait to let them get use to us?
