Hello! Any advice/suggestions on this would be greatly appreciated!

My twins are now 5 months old (4 months adjusted) and both learned the joy of rolling from back to belly. While exciting, it has put their napping and sleeping down the hole! We had just finally settled into feeling that their napping and overnight sleeping were in a good place and now this...
When they are put down in their crib they want to flip and then they get mad because they seem to have forgotten how to roll back onto their backs and they don't turn their heads while lying flat on their belly - they either face plant or are in push up position (unhappy in both!)

Did you have to teach your little ones to sleep on their tummies (turning faces side to side) if they turn onto their tummies while sleeping? Or did they eventually figure it out themselves? Right now we have had to resort to either swaddling them up again or rocking them back to sleep - which we haven't done in a while! We know that sleep training is coming up soon as we have no desire to go back to rocking them to sleep, but do we wait until they are more comfortable being on their bellies or remember how to turn back onto their backs? I'm a little weary of leaving them to cry if they're just face planted nose down on the crib unsure of what to do.

We are also simultaneously trying to swaddle/miracle blanket wean since we don't want it to pose a danger to them... this has been a challenge as well. Lots going on in this casa de geminis!
