I’m losing my mind and need help.

About, I’d say 6 or 7 months ago, maybe longer, my 19 month old has started to find comfort in playing with and aggressivly pulling my hair. All day long, and at night I co sleep with her and she spends all night long yanking and pulling my hair and when she can’t get to it, she screams and cries until she can get ahold of it. I seriously don’t know what to do. I’ve told her no, I’ve tapped her hand, I put her down on the floor when she doesn’t stop. I’m so lost to what to do. It’s mentally driving me insane. And I’ve already experienced a lot of hair loss after having her, so she’s not making it easy to growing my hair back when she’s yanking it out. Also, I’m a SAHM so during the day I can’t get a break from it. I seriously am about to cut a piece of my hair and give it to her to hold on to. My first born never did anything like this. And I don’t see her growing out of it anytime soon. Anything will help.
