Sleeping Baby Help

Samantha8604

My son is 10 months old today. He has normally been a pretty good sleeper, he would get me up maybe once or twice during the night eat and go right back to sleep. A few weeks ago he started to not nap as well at daycare, a few days he would go all day with out napping but you could tell he was dead tired. Then 2 weeks ago we went on vacation and shared a hotel room with my brother and sister in-law and there 1 year old. Now we did have a pack n play for him to sleep in however I was to worried that I wouldn't be able to get to him and quiet him down fast enough before he would wake up his cousin so he just slept in bed with us. BIG MISTAKE . Now he hates sleeping in his crib and will scream bloody murder when he wakes up in it.  What do i do?? As soon as we pick up him hes totally fine so I know nothing is really wrong with him. We have been trying to let him fuss it out but he screams so loud I'm afraid hes going to hurt his throat. Is it wrong to let him cry it out? Also how long is to long for him to cry? Are there any other things I can try. I really need to break the habit of him sleeping with us.
