I have our first little girl in may i don't get along with my family and his doesn't let me breathe!?

What are some way to cope with his family? they never cared me ever until i got pregnant then its was like they loved me? My husband and i are very private people we aren't hermits but we just don't like to be bothered by his crazy clingy needy family but now his family expecially his mom won't let me breathe having conversations with my belly always telling me her plans with the her grandchild? i feel like they want only the baby not me? What can i do to have some patience and accept them? I feel like i am losing my mind because my family can go months with out talking to me but they can't go one day? If i don't answer they call and call and call! i have told them i m resting and i need some quiet time and they continue!
