We just returned from a week long trip to see family. Before the trip, our 2 year old would happily go down for the night in his crib, read a few books and pass out until morning. At my in laws home, he wasn't happy at all about bedtime, and I laid on the floor next to the crib until he fell asleep.

Now upon our return home, he refuses to fall asleep alone. DH is up in his room now, watching LO read books in his crib until he falls asleep. This was after 15 minutes of screaming, an interval where I rocked and sang to him and put him back down, and then another 10 minutes of screaming.

Will he get back into his routine, or any tips on how to get him back to happily going to sleep on his own out there?
