My son’s friend’s mum has died and he knew her well. He’s only 7 and is heartbroken. He has been crying all evening and saying things like ‘she was so nice’ and ‘her son will only know her for 7 years’. I’m trying to say the right things and give him lots of cuddles but he’s never known anyone else who has died and this lady was so kind and lovely to him. Any wisdom? Hand hold?
