Girls, hello. My son is two months old and has been bothered by his tummy. He sleeps well lying on me or snuggled in a sling against my chest. In the stroller he loves to sleep, but because of his tummy he can't fall asleep. I was putting him down, he cried and couldn't fall asleep. I turned him over onto his stomach so he could lie down, and he immediately fell asleep. Now I don't know what to do. Did someone put such babies to sleep on their stomachs? He's right there in view - sleeping in the stroller under the window in the yard, the window in the kitchen. I'm cooking and watching him. The older one also slept on his stomach
