Well, unfortunately you kinda messed up by taking him out after a while. Now you have a situation where he's going to cry and cry for a long time because he's made the realization that you have come in when he screams. So, the best thing to do is to lay him down, tell him you love him and you'll see him when he wakes up. Walk out and let him cry it out. If the crying is really bothering you, shut his door, he'll be fine. Put a fan in the hall outside his door to help with the noise. You have to retrain him that when he is put into his crib, it's time for him to sleep. The first day is going to be HARD because of the fact that you've given in and gone in and taken him out. The second day will be hard to, but by the third day, he will be doing a lot better. Remember when you are letting him cry it out that kids NEED sleep. He may not like it, but after he realizes that you're not coming back in until he sleeps, he'll start getting those much needed naps in again, and be a much happier baby throughout the day because he won't be so tired!
