Baby not sleeping at 10.5 months.... Help!!! What can I do

I have a 10.5 month old baby and he is not sleeping... I don't know why. I always give him 2 naps a day the first at around 11 and the second around 5. He usually ends up going to bed at around 9-10. Now I just moved back in with my parents and since then I have not gotten my baby to sleep here for a solid night yet and it's been 2 weeks... I have not changed his scheduale aroun or anything ido the same routine every night that I have always done for him. He wakes up every hour in his crib and usually I will just put him to sleep with me and he will be zonked out in the first 5 minutes. But now he is always squirmy and that keeps me awake. I try putting him back in his crib and he wakes up again about half hour later. I gve him a bottle and he will be quiet while he drinks it but then he will starts fussing again shortly after. Now I know this may sound funny, but this house is the only place he won't sleep a solid night at. I was at my apartment about a week and a half ago for 4 nights and he slept through every night no problem. I come back here and he won't sleep. And here he has his crib, where as at my apartment he only had a playpen... I don't know what to do to make him sleep but I need help!
