The Pediatrician said baby needs tummy time. So I did it. Yes, the kid screamed and didn’t like it and so forth but it’s like an adult going to the gym and working out. You just have to do it over and over to get stronger.
You get the baby’s favorite toy and you try to have the baby play with it while they are on their tummy. Put a blanket on the floor and let them do it, from 2 months on they should be doing tummy once a day for at least 5 minutes. Every week increase the length of time. Because the baby is crying that doesn’t mean you pick them up, let me cry, eventually the baby will be doing 30+ minutes and then they will roll over and then crawling.
Remember you are the parent, you know more than the baby.
