I met her through my daughters club and offered her a lift home a couple of times. She them put her DD in my DD's school and since then she has driven me mad. I have tried to avoid her but she waits with sweets for my DD. She sees my Sis and tells her all sorts of things and then tells me different next time I see her, her DD hits my DD in the face and she does nothing about it and now she has attempted to pick up my DD from school "as a surprise" for me. I had called the school to say I was running a couple of minutes late and she actually told them that I had asked her to pick her up. Thankfully they didn't let her go as I had not put her name down. I went mad. Please help!!
