just booked dd bday party how do you know who to invite there are 30 in her class no way are they all coming. Do i just ask the girls then what happens to the boys that asked her to their party. I have also asked her who she would like to come and i may as well ask the whole class. This is my first bday party for her she only started school this year, have thought about asking just the children that were in her nursery class but again what about the ones that have had her at their party, its v expensive so i need to keep the numbers down.
