Hi all - I'm new to mumsnet and have been amazed at the massive community of support I see here. My ds1 is 3yrs 4 mnths and was dx with benign hypotonia at 11 months. His problems have always seemed to be physical and he makes slow progress but seems a happy young man. However, I watch his friends develop and he seems to be falling behind with other areas. He is proving impossible to potty train and doesn't seem to understand what I am asking of him. Basic understanding of simple things seems beyond him e.g. was trying to play basic dominoes with him today and it's about matching colours. When I talk him though what he needs to do he can follow instructions but doesn't then seem to make the connection and match the colours by himself. My 18mnth old is better than him at the shape sorter! He learns and repeats what he hears well but I often don't think he really understands what he's saying, or is able to apply his knowledge. What should a child of his age be capable of? Am I just being paranoid and looking for problems? At what age can you tell a child might have some basic learning difficulties? Sorry - lots of questions I know!
