How do you change the bassinet?

Once the baby is born, it's basically one with the bassinet and you can't switch them out at that point. 

It stinks, it actually makes it hard to decorate exactly as you want if you play rotationally unless you play with aging and neighborhood stories off, which is what I do.  I do wish the babies weren't as connected to the bassinets though, not everyone wants to play that way, but I've also had mishaps myself where I'd have everything planned out, decorated and ready for the baby when it's born and then the game would pop twins and I'd suddenly have the perfect specifically chosen bassinet for twin A and a generic bassinet for twin B and it would just throw everything off for me.  And I would end up aging them up rather than enjoying playing them through that life stage just so I could get rid of the bassinets altogether.  I guess that would be another option, just age them up to infant and put in a crib that matches the room decor, but it still wouldn't let you enjoy that newborn life stage.

Ah well. At least it's not a long nooboo wait time. Thanks for letting me know!

To the best of my knowledge, I'm very sorry to say it isn't possible. You almost have to have the bassinet of preference in the home before the baby is born. With the exception of an alien birth, that is. Perhaps, another player far more clever than me will have an answer for you.
