Is this like the let them cry themselves to sleep for a night or two (hopefully) plan?
Yeah more or less.
The key concepts are:
-Depending on the age, Baby WANTS to sleep. They only wake at night and cry for attention to rock or nurse because that is the only way they know how to get back to sleep. (The exception is when they are a young baby that actually needs to feed and are hungry).
-babies will cry, it doesn't hurt them (in my opinion so long as they haven't entered that super-stressed cry - you should learn the tones and pitch of your child to determine what is just annoyance cry and what is actually something more serious).
So the program encourages babies to not fear sleep time. Like adults, they need a routine before bed so they can see sleep time approaching and prepare themselves mentally. Also by making sure they actually fall asleep themselves in their cot, they hopefully learn to not fear it. Never have them actually fall asleep while nursing or rocking.
The program essentially has you set up a routine and for the first three nights there will be some crying and you just make your presence known while they fall asleep in their cot. The first three nights are toughest and most important to stick 100% to the routine. You can sooth them, pick them up if ultimately necessary, but try to reduce your rocking and nursing, especially to sleep. Over the course later you reduce your presence.
So yeah, it's really simple and makes sense. We were more or less doing something 80% similar anyway, but we learned the key point of not having them actually fall asleep during the nursing and rocking, which we still kinda do as part of the routine and soothing, just don't let baby use them to get to sleep.
The course actually has some other tips and stuff, and variations depending on the age of the child, but from what I gather I've listed the key concepts above.
Again I don't subscribe to magic bullets ever, I recommend taking the ideas and making them your own. Of course the program itself speaks of being strict at certain parts. I can't say for sure if anything we did in accordance to the guidelines was anything that worked, all we know is that we moved from baby crying in the cot as soon as we put her down a lot to my and sleeping more solidly.
It could simply be us as parents hardening up and being less worried ourselves.
Straightening out a bedtime routine that you stick to and keeping them awake to fall asleep on their own does make a whole lot of sense though - before we'd have a routine but it was very short and we didn't stick to it 100%. Baby now knows if we follow a particular activity with another one or two in that order, it will soon be cot time for sleep. She doesn't fight it as much as she used to. If at all.
For the record our baby is now 8 months. We've been trying the concepts for a couple weeks. Like I said, who knows, maybe she was simply ready to do all of this on her own, and it's all a coincidence. But I've heard of people just hoping things are just a phase and waiting for them to straighten out on their own and it never happening. *shrugs* can't hurt to try, right?
