I had mine at 34wks so I think 32wks is good. We had a game where everyone wrote down what day/time/weight/sex the baby would be and then the person who was closest got a little prize (was all anyone was interested in after I gave birth - who won) Did the guess how many squares of toilet paper would go around mum-2-B's belly did fasted nappy change game and find the nappy pins in rice.

Food - in this weather lots of fruit and light snacks dips etc, sandwhiches. My mum made a cake covered in those tiny baby dolls you get from the craft shop (looked a bit strange but a nice idea)

Have fun
