I know its hard for parents to leave job, especially when new job :O is there a dad ?? Anyhow the playpen in the playroom is best idea, but after few days, I wouldnt let her sleep whenever ! Here its all open basement and naptime is in playroom so she would be in playpen in playroom with others.

If she cries the whole time because she is not alone, well then its endure or call parents to give me a break really... even give HER a break !
