My son is almost there but still not fully grasped it!
Mine only just did it today she'll be 6 months on the 11th
Mine hasn’t done it he’s 5 months
My little one can roll onto both sides and from tummy to back. Still yet to roll from back to tummy, he just stops on his sides then rolls back x
Mine is the same. Gets half way over and can't figure out the rest. They'll get there! Tummy to back is no issue. Thing is, he hates being on his belly so he's going to be absolutely livid once he finally manages to roll back to tummy!
Our LB rolls from tummy to back on both sides just before he turned four months. I used the techniques from this video to teach him: https://youtu.be/NCBEYie42iU?si=vrLe4aBTMG0n7ST7
