Ok, my son turns 4 this summer and I'm stumped for a theme.
Themes help me tie things together and come up with games etc, so I need a theme. So far we've had super heroes (at home), pirates (at the local soft play), and paw patrol (home again). He's got his own interests that I can draw on, but he's so interchangeable with his favourite things right now I don't want to do a character themed party because you can guarantee he will go off it the day before the event.
Locally there are halls for hire etc, and I'd rather have an outside venue if possible because I'm really not looking forward to having a house full of people that I can't escape from.
Does anyone have any interesting ideas I can pinch?
