Last year for Bailey's 3rd Birthday, we had a mermaid theme. We didn't need to go overboard with the party planning as the look was easily achieved with all the pretty printables for the invitations, bunting, food labels and favour tags. The only thing we planned that didn't work out was the weather: so instead of swimming we planned games inside. Hopefully, your little mermaid party will not get rained out!
