Absolutely not, just like the others said! We are planning a little celebration with immediate family - just balloons and a cake (egg free, gluten free, reduced sugar.... Might as well just slap some berries on some cardboard and be done with it I think), very low key!
My little one is having her first actual birthday party this year, she's 4 this year. Last year for her third birthday we had a few of her closest friends round for snacks and playing in the garden.. She had a great time and didn't get overwhelmed!
