I think its fine :) as long as the people you love are there with you to celebrate ur baby i think it doesnt matter! The family on my hubbys side will do it after the baby is born as we live so far away and will only visit them all in the new years. But as long as everyone is happy i think thats all that matters :) have lots of fun!
I'm having mine at 31 wks! And my friend is having hers at 36 wks! Your fine :)
