Some MN wisdom required please as this must be quite a common situation. Dd has been invited to her close friend's bday party. The friend is having a joint do with another girl, who my DD knows but isn't really friends with. Different class at school, don't play together at break and have never had out of school play dates etc. I'm fairly sure if this girl were having a solo party my DD wouldn't be invited for these reasons.
So, my thinking is that I only buy a gift for DDs friend, and maybe a card for the other Bday girl. DH things that's unreasonable and I should get gifts for both girls. So is there any etiquette on this? AIBU?
