We went to the pediatrician today for our 9 month old's checkup, and based on his current sleep schedule (sleeping from ~7:30PM to 5:30AM, with multiple 30min to 1hr wakeups), the pediatrician told us that we need to try the Extinction method (also called Cry it Out or CIO).
The only problem is that we are going away in five days for a three night trip. I have been told that you can't do Cry it Out if you sleep in the same room (because it's too emotionally distressing if they can see you while you ignore them).
I am worried that if we do CIO for the next five nights, then go back to the old routine (multiple wake ups with parent soothing) at the hotel, that he will revert back when we get home, and need to be retrained.
Does it make sense to start CIO now, or wait until we get back from the trip?
