DD is turning 6 and DS is turning 4 and they are both really into 'The Trash packs' so im thinking of having a joint birthday party for them this year. Im kinda thinking of taking advantage of the fact they like the same thing atm...this will probably not be the case in years to come.

Their birthdays are 16 dec and 4 jan so close but with xmas etc in between. So because its so close to xmas, when should we do it??

Usually we do alternate years for birthday parties...as in one year DD gets a party and DS gets sizzler with 2 friends and vice versa the next year.

Have you had a joint birthday party?? How does it work?? Then what do you do on each of their actually birthdays??
