Oh boy, thanks for posting. Having the exact same problem over here! Week 3! Have tried switching rooms (the furthest away!); darkened room, white noise...he still only sleeps for 30 mins. then cries the rest. Of course, then sleeps 6pm to 6am at home for the parents. Kinda sad, really. I've asked them to shortened this out to help me but really doubt it's happening (he's super busy, first drop off, last pick-up). You might want to investigate his sleep schedule at home?
