crazy mil

What would you do if you told your mil that you're pregnant but only 6 weeks. Then you go to her house and you see a crib, clothes, diapers, baby bath and a car seat. You ask her what's it for and she says "so when the baby stays over here". You ask what!? And she says that she's going to get the baby once he/she's born right out the hospital. To keep overnight without you there and that she'll be getting your baby every night besides Saturdays and Sundays. What are you going to say and do?
