Hi Kassee, I made a thread about this a little while ago
http://www.theanswerb.../Question1150946.html
And I keep getting mixed reviews on whether it'd work or not, and the general conclusion I drew along with others is that having your baby literally in the office next to you would decrease work output and attention to work from the the parent and other workers around but everyone agreed that a creche on the same floor or in the same building would be the best idea as the baby/child could be picked up and dropped off as the parent comes into and leaves work and they'd have peace of mind and this would more than likely increase work output.
