We decided to take the plunge and sleep train out 5 month old son.

We placed him in his crib at 7pm. The crying started at 7:08pm, and was constant. There were no breaks and we did 5 minute check-ins the whole time. At 8:08pm, I decided to go pick him up because the crying was not letting up and I noticed he was soaking in sweat. I changed his Pjs, put him back in the crib, and he miraculously fell asleep at 8:15pm for 20 minutes. At 8:36pm he woke up and started crying. We continued the 5 minute checks and he fell asleep at 9:45 after over an hour of straight crying. This time he slept for 25 minutes. After this second wake up he cried for another hour straight, that's 3 hour total, and I couldn't take it anymore so we reverted back and put him in the RnP. He fell asleep immediately and only had one wake up, nursed, and woke up this morning at 6:30am. I know we messed up but 3 hours of crying was hard.

Please help. Did I totally mess up by not completing the training last night? Do we try again tonight? Do I wait a few days, a week? Any suggestions are greatly appreciated. Thanks!
