I relied on HelloBee a lot in preparation for sleep training, so wanted to share our log to the degree it is helpful for others. I have to say I honestly never believed this would work, but was so exhausted I figured I had to try.

The setup: Our baby boy is 17 weeks old. For the first ~month of his life he nursed to sleep, and after that he would only fall asleep while being rocked with his pacifier in his mouth. We swaddled him and would place him in his rock n play, where he would typically sleep no longer than 45 minutes before crying out. When he wasn't hungry, usually all it took was reinserting his pacifier. But it was getting reeeeeeealy old reinserting that paci all night long. He was usually down by 7, ate and 12 and 3, and up for day at 6. The eating wasn't bad but he was barely eating anything, and he was so restless in between feeds too. I actually tried cosleeping to see if that would soothe him, but it didn't help at all. And I was miserable.

So we did the basics -- get a good bedtime routine in place (bath, bottle, book, white noise, etc.). We decided to drop all of his crutches at once: in crib, no swaddle, no paci. Harsh, I know, but I figured a little pain all at once would be better than spreading it out.

Going in, we planned to keep one feed between 12-3 (figuring we could cut that over time).

Here is our log...

Night one:
7pm: In bed. I sat in there with him to try to soothe/comfort. After 45 minutes of on-and-off crying it appeared to make no difference, and I was doubting myself. So I left room to regroup with my husband. Within 5 minutes of me leaving he was asleep. After that we only went in to do checks once or twice after ~20 minutes of crying. It just seemed to make him madder so we left him alone.
7:50: Asleep
8:20: Awake, crying.
8:40: Asleep
12:00: Awake, crying. I did a feed.
12:20: Back down awake, crying.
12:40: Asleep
4:00: Up, crying. After 10 minutes of it I caved and fed him, even though we had planned on only one feed.
4:20: Back down after eating, and fell asleep with NO CRYING.
7:00: We woke him up for the day by turning the lights on. Happy as could be

(Note we also did naps along with this. For 75% of naps he went down with no crying and would only stir an fuss for a few minutes around 45 minutes before resettling himself and sleeping for a 1.5 hour nap. The other 25% of the time he fussed on and off and we gave up after 45 minutes of trying.)

Night two:
6:30pm: Down, and fell asleep within 10 minutes with no crying!
11:00pm: Woke up crying. I wanted to feed but my husband said no, we should wait until midnight. This one was torture. He cried on-and-off for almost 40 minutes.
11:40pm: Asleep
3:15am: Awake, some fussing. We started to go into feed but he fell asleep within 10-15 minutes (we were kind of groggy).
3:30am: Back asleep
5:30am: Up, crying, and this it he longest he had ever gone without eating so we got him up early. I should note that he didn't even really seem that ravenous at this feed. He seemed just fine.

Night three:
6:30: In bed, asleep in less than 10 minutes with no crying.
4:00: I wake up to look at the monitor and am in complete SHOCK that we haven't heard him all night. At this point I get out of bed because my body is not used to sleeping so long :). I decide to watch him like a hawk on the monitor and it is fascinating to watch him stir occasionally and resettle himself so easily.
5:30: Light crying and fussing for a bit. We really want to try to see if he can go 12 hours so I let him be.
5:45: Back asleep
6:30: Turn on lights in the room to get him up for the day.

So that's where we are now. I am sure there will be some regression but I am so thrilled with where we are. He has been a challenging baby from the start, never a good sleeper (never more than 5 hours on his own, and more typically 3), and a very intense crier when he was unhappy. If this can work so well for him, then I really hope other exhausted mamas give it at least a try.

The best part is that he is so happy and bubbly when I get him up, AND I have so much more energy to play with him when he is awake because we get those much-needed breaks for naps and at night.

Good luck to others! I really never thought we would get here.
