My 6 month old can only roll back to front, he did it a few times when he was 5 months then nothing until last week now he never stays on his back he just rolls to the front constantly, even when trying to change his nappy. However once in the front after a couple minutes he starts crying , I’m guessing as he can’t get back? And he hates being on his tummy so I’m surprised he keeps going there. How can I help him get back over? And is this it now is he never going ti stay still 😂
