Hi everyone. I am new here but just really need some advice. My ds is 5 years old and he's just started primary school, we delayed his start date due to his learning and development being behind where it should be. In his second year at preschool he made a lot of progress however still a little behind. We have taken him to the piedatrician and ds has had some genetic tests where they found he had some chromosomes missing and he is seeing a geneticist next April when we will find out more so just taking such a long time to get any answers. I'm so worried about him and over the summer holiday he was really well behaved but for the last couple of weeks at school his teacher has been telling me he's been really naughty and biting and hiting other children. I feel so upset and stressed out. Can anyone relate to this? Any advice? Xx
