Same. You definitely can.. Just not for long.. Like these ladies are saying, but also you don't HAVE TO lay on your left 24/7 but it is recommended you lay on your left sometimes.. My favorite side to sleep is my right side..

you can. but not a long period of time. I still find myself on my back

You don't have to. Your not supposed to lay on your back all night. But most of us move and change positions at night. I slept on my back sometimes. And he is fine. It's not that you can NEVER lay on your side.

Okay I wasn't told that but I had heard people say it didn't know why.

left side, yep.

So you must always lay on your sides?
