Ds2 (4) has had tearful moments over the idea that ds1 (6) will get a party bag at his friend's (McDonalds) party. If I take him I know they will both ask for an extra party bag and it could be highly embarrassing, but OTOH will the hosts really begrudge giving him one? they always seem to have extra ones and I do give bags to siblings if they appear. Also we have given a substantial present.
