My son is just over 8 months old. And he is not sitting up on his own yet, not even close. Whenever I sit him down he arches his back so much, he scoots forward... Then topples over. I've tried sitting behind him, to help him out a bit, but no success! I'm worried he's not reaching important milestones! Is this normal? Or am I right to worry?
