My DS was 5 weeks premature and we have noticed certain issues with his development. He is 13 months now and has started to crawl and does stand up by holding anything which is in the way but when he walks with support, he tends to apply pressure on his paws and lifts his foot up, so practically he never has put his foot down till date- Not sure if it is lack of confidence but I cannot understand if this could be an issue.
He also struggles to relate to toys, he rather play with anything apart from toys for him.
