LO has been biting me and pulling my hair lately. She bites DH but it's not as often. She isn't doing this in response to something she doesn't like, she's doing it because she thinks it's funny and she's just playing around. It hurts but it doesn't really effect me. However, I just don't want her to think it's okay to do this to other kids.

I tried yelling really loudly during both behaviors (a couple of times not on purpose, it just hurt those times). She thinks it's funnier when I do that. Does anyone have any other suggestions? What else can I do to curb this behavior before she starts doing this to other kids?

Edit: We have also firmly told her no and tried to make her realize it's not acceptable. She's 15 months old.
