Overbearing mothers...

Abby

So my mom who lives 4 hours away and has never had a close relationship with me told me today shes planning on buying a camper and posting up in my yard when the baby is born. I think she thinks i need her help but me and my boyfriend are perfectly capable and will both have plenty of time off work to be home together raising our son and I dont know how to politely tell her that I dont want her to do that😔
