How do I stop my 15-month old from biting?!

My daughter is a biter. I know she’s teething and she has plenty of teething toys, pacifiers, I even give her Motrin sometimes (very seldom) if she’s fussy and biting everything.

She seems to have a problem pulling hair and BITING my arm or shoulder as hard as she can, to the point it leaves bruises. I get so mad but there’s not much I can do about it, she’s a toddler and she doesn’t know any better.

How do I break her from this habit of biting? I’m scared to put her in daycare at all because of this!
