I have a 22 month old and we went through the same thing when she was about 1. She would cry, I would check and make sure that everything was o.k. with her, and she would still cry. She wanted me to pick her up everytime. My Dr. said that it was a phase and when she cried, go in, pick her up, tell her you love her,tell her it's night night time, give her a kiss and put her back in the bed . Let her cry and after 10 min.(which is long to me, we usually waited 7 min. or so) go back in and do the same thing over. Eventually, the Dr. said that she would stop and start sleeping through the night again. Amazingly, it worked! And it worked in 2 night's. As far as having company, I know how you feel b/c you never want to disturb anyone, but depending on how long they stay, I would tell them what's happening. It may be rough for everyone the first few night's but it's definitly worth it when they start sleeping again. Hope this helps, good luck!
