Thanks ladies! Some great ideas.
It needs to be free, or very close to it as his party was super exxy (well for us it was). - At a play centre ZF LOL
Park for lunch and a play could be good then his choice for dinner and we have LOADS of left over birthday cake.

I'm not really sure what else we could do. I would bake something with him but we have no oven (or kitchen actually ).
Maybe some painting, we don't do that very often.
Make a Cheezel necklace (we have a packet in the cupboard)? lol
Lots of mummy attention with no distractions? That has been lacking lately.

I feel like most of it is things I should be doing anyway but just haven't been capable of lately because Ive been sick. I really wanted something Birthday-ish...

Wonder if I could find some cheap markers that we could use to draw faces/ animals on balloons... Or paint balloons.. that might be an outside activity. haha or paint WITH balloons... or cars... hmm some kind of painting could be good as long as its not wet outside. Get in the bath and paint each other? LOL
