How do you deal with it? I just Googled "18m Sleep Regression" and obviously there are a variety of "techniques". I know he will go to sleep if I lay down with him. If this stage is going to last 1-2 months, do I get into that habit now and give up my only "free time" during the day or do I listen to him cry for hours on end? I just picked him up after 20 minutes of crying and he passed out. Tried to put him down and we're back to 20 minutes of screaming. He's clearly exhausted. HELP!?
