She comes on her own as FIL and MIL are divorced. She doesn't help except do a bit of washing up and iron and generally just is THERE invading our privacy and creating work. She doesn't change nappies, bath the children, help with cooking or play with the children except reading to them. The worst thing is she stays on days when we are both going to work - it is a nightmare in the mornings getting the children to nursery and getting ourselves out of the door as it is and she just gets in the way. She has just retired and I feel we have to nip this staying forever thing in the bud now. I don't have anything in common with her, she isn't a bad person but I just don't want her around this much. Help?
