My dd is in nursery now. She lives with me, no contact with father for nearly 2 months (his choice). I put both of us as parents on the registration form. I have been the only person to pick or drop her off however. I'm worried her father might turn up and take the away - obviously very distressing for her as she doesn't know him. He is on birth cert. Can I tell nursery to not allow him to pick her up? Haven't said anything so far.
