I have a question about rolling over. Tristan is nearly six and a half months old - he can roll from his front to his back fairly easily and from his back to his side, but cannot really move from his back to his front yet. It is like he cannot be bothered! Usually, he is too concerned with trying to eat his feet! We try to give him heaps of mat time and tummy time. Should I be worried? I know they say that you shouldn't compare your baby's development with other babies but I am still a bit worried. In other areas he is doing really well, like he can pretty much sit up on his own now and he babbles away making heaps of sounds - but the rolling thing worries me.
