My lifelong best friend and I have sons of the same age (both are 5).
My son is very lively, outgoing, loves singing, dancing, rolling around outside etc. He hardly ever sits stills, he's so active and always doing stuff. Best friend's son is very quiet, and never seems keen to play when the visit our house. He has quite bad asthma and eczema, so she doesn't like him playing out in cold weather or running around, says it triggers his conditions too much. He's not allowed chocolate, sweets or anything like that. No fizzy drinks either. I allow my son to have the occasional drink of coke or chocolate bar as a treat, don't see any harm in it tbh. Because the other boy hardly ever plays or wants to take part in anything when they visit, my son has recently starting saying he doesn't want him coming over any more :( I've tried explaining that the little boy is just different to him and that he still needs to be kind and considerate towards him and his asthma and health issues but it's hard getting a 5 year old to understand this. He just sees it that the boy doesn't really want to play with him and isn't interested in his toys and isn't allowed any treats :( I don't want these differences causing issues between them because I'm very close to my best friend and would like our sons to be friends. Anyone in similar situations?
