I hope those of you with older children can help me with a concern I have. My 9.5 month old boy is developing very slowly. He has sat up for the last couple of months, but he does not even attempt to crawl. In fact, he hardly moves, he just learnt to turn from his tummy to his back last week and only does it when I put him on his tummy. He is a very calm baby, and although he is developing at other levels, his gross motor skills are not in line with other babies his age.
Do you think there is a link between this and his level of intelligence?
