My previously very brave 6 year old has suddenly developed very bad separation anxiety. He’s never ever cried when we’ve left him before, not in nursery. He goes to beavers and after his first ever time going he did a big beavers sleepover and wasn’t at all worried...that was a while ago just to show how brave he was. But now he cries every morning going to school, going to beavers, going to swimming etc things he loved before. Leaving him at bedtime is a big struggle too (never been a problem before). He says he misses me so much it gives him tummy ache a lot...it’s making him so scared to leave me because he knows his tummy will hurt. Once he’s at school or at a club he’s fine but the thought of leaving me makes him feel physically unwell. My mum recently moved away which we think can be the only reason this has stated but we have reassured him we are never going to move away from him. He doesn't seem sad when talking about my mum or to my mum. He knows he can ring anytime. How do we help get over separation anxiety and tummy aches from worrying. I could cope with him just crying but the tummy aches are really getting to him/us. Please help with any advice or share your experiences with separation anxiety. We don’t let him see us upset but it’s really upsetting us all. At drop offs I act confident and happy, kiss and leave straight away. Told him it’s ok to miss me but that it’s not ok to let it get in the way of him learning and having fun. He has a worry monster.
