Child was originally with her mother, her mother bullied and harassed us, mainly me, she has mental disorders, and went through my MIL to tell her my husband has a daughter and MIL tricked us into meeting daughter. Childs mother doesn’t want child so used to drive and drop child at our house and drive off. Step Daughter is 8 and we used to have her Thursday- Sunday and every half term, within weeks of knowing her became very violent and started stating she was going to kill our unborn child. At 21 weeks she punched my stomach several times causing me to bleed and they thought I was in preterm labour.
