I'm a lone parent. My youngest age 4 has been invited to a birthday party at a playbarn. His sister age 7 can't be covered childcare wise.
Do I just take her along too and allow her to join in (obv not the party food part) or pay separately for her entrance fee?
I'm confused as the previous playbarn party for my eldest, the mother particularly said that it was ok to bring a sibling.
What's the etiquette?
