Hello, we're at 35-36 weeks. Ultrasound said the baby is in breech position ??‍♀️??‍♀️ I'm very upset. The older child was also in breech position, didn't turn and I gave birth vaginally. The doctor said to do special exercises, talk to the baby by massaging my belly and so on. But what did I want to ask? Can sleeping position affect breech position? I always lie on my right side, but online it says you should lie on your left side. Could the baby not turn because I sleep on my right side? Or even could he be positioned vaginally because of that? What helped others? Who had breech position? Please advise ????
