@Shaz, thanks for posting that link. I guess then it's up to the people collecting
I'm going with her pose so mine is a girl because of that - but it seems Hasbro genuinely don't have a preference so I guess the him/her option on the poll is now the most correct
I mean, Baby Schoolbag is definitely a boy, and in the UK, Sniffles from Sniffles and Snookums is also a boy, though those are both "female" poses. So yeah....it's not an exact science.
(I am pretty sure I have at least one book where AJ is male in one print and female in the reprint...maybe Bubbles too, possibly...)
