My 21 year old son is obsessed with teddy bears, he’s got 2 six foot ones and about 20 on his bed. I discussed with him that he can’t have anymore as it’s becoming unhealthy which he accepted at the time but now wants 3 more, I’ve said no and he’s so angry and upset. I know he takes comfort from them and would never take away any he has already as he regards them as his friends and comfort, any advise?
