2 siblings aged 5 and 8 with quite a lot of rivalry between them. Younger one breaks his arm quite badly and is in a long cast and can't do a lot of his usual activities. my DM generously says she is going to send him a box with toys/ activity books/ a new lego set etc. I know this will cause intense jealousy from older brother (he is already pretty jealous of him and he is now getting lots and lots of attention post broken arm.) . I was hoping that GM would offer to send a little something in there for his brother too (money genuinely no object here) - nothing major but maybe a colouring book or similar but she won't because she believes big brother should feel sorry for little brother and happy that for him that he has got presents etc. I would at this point rather she just didn't send anythign to either of them as it will cause way more trouble than it's worth. Genuinely curious as to whether I AIBU here and not teaching DS1 to be kind (I'm exhausted and keen to avoid an argument) or whether it is insensitive of DM. Opinions welcome.
