My wife is 30 weeks pregnant currently. She had cervical stich at 22 weeks of pregnancy and on complete bed rest thenafter. Firstly we want to know best position for her to sleep. When she changes sides while sleeping fetus also moves to respective down side of stomach. Is it normal? and if she is in sleep and baby comes down to same side, any pressure on stomach can harm the baby? Thank you very much in advance for assistance.
