Toddler biting! Help!

Brittany

My son is 2 1/2. He has recently started biting at daycare. He bit twice in the last week. He has bit a couple other times over the last few months. He will be kicked out if it becomes repetitive. Anyone have any tricks? He doesn’t do it at home. It normally happens when they are fighting over toys. He is getting in 2 yr molars and is extra fussy. I will take any advice I can get.
