DS wants to do a planned activity for his birthday (turning six).
Places for said activity are limited to five plus DS
His sister has no interest so we have said he can invite who he wants. He wants three school friends and two from extra curricular activities.
Told my Mum in passing who has told my sister and she is really put out her children aren't invited. DS loves his cousins but there is an age gap and this is his first 'friends' party.
His own sister isn't going but apparently I seem to have caused WW3. Have I missed family etiquette. They have been invited to previous years and will be invited for family tea.
I'm not cancelling/changing plans but DH is now on the back foot. I really don't think I'm unreasonable... am I? It's what DS WANTS to do.
