I'm having a joint birthday party for my 5 and 2 yr olds. I was going to make cute joint invites with "x is 5, y is 2" theme but my mother thinks people (particularly school friends) will decline because they will think I expect two gifts. This hadn't crossed my mind and my Mum has form for assuming she's being taken advantage of by all people at all times, so aibu to put both children on all invites?
