Waking & crying

My 1yo all of a sudden is sleeping so terrible. Went from waking once in AM to 2-4 times at  night. Won't take her cup of milk and will just cry and cry. Pick her up and she's fine. Set her back in crib and cries again.. Do I just let her cry it out? I think she is getting "spoiled". Since it's been going on this week I took and slept on the couch with her 2 nights. She just started again and I let her cry it out. 10 minutes, drank her bottle and she's sleeping again.. Should I let her cry it out everytime? I do go in there right when she starts than I leave.
