DS (3) is allergic to cats, he can't be in a house where one lives without his face & eyes swelling up. My mum has 2 cats so we can't visit her and I don't like the idea of giving him antihistamine medication so we can visit (DH takes them for hayfever and they make him quite drowsy).
DD goes to stay at her Grandma's house but DS will never get the chance unless she gets rid of her cats. I've asked her whether she would be prepared to and she says perhaps but that she wouldn't be able to find anyone to have them, I get the feeling she doesn't really want to as she is quite happy with things the way they are.
I respect her wishes but can't help feeling sad that DS is going to have no memories of going to visit his Grandma, AIBU?
