Hey Mari, thanks for the link, I've actually looked at this a few times and thought that I was doing Wi/Wo properly, but looked again last night, and realized that I probably was not leaving soon enough.
SO, last night DH put DS to bed and needed a couple of PDs and pats, but nothing outrageous. He was out by 7:15 (took a big 2.5 hour nap at daycare from 12:30 till 3:00). He stirred a bit at about 9:30, but I could hear him on the monitor and it sounded like he was dreaming so I left him alone, and he went back to sleep.
Then, at about 11:00 he stirred again (so that 3.75 hours after bed time) and woke fully. So I went in and PD, offered Paci and did Wi/Wo for about 15 minutes. Then, I got him his cup and he took a big drink, and we did another 15 mins or so of Wi/Wo. I stayed "out" while he was whining, and doing his frustrated chatter, and only went in after 5 seconds of real crying (there honestly wasn't much of that). About 30-40 minutes in, he started to really cry, and I thought that maybe he would like some tylenol for teeth, which I gave him - and right after that, he lay down, I did Wi/Wo maybe for 2-3 more times, and he settled into chatting and then finally just went to sleep ... I should note I was not even in the hall anymore, went back to bed and listened on monitor.
He then slept until 5:45 - and I left him to chat (even though it was his frustrated chat) until 6. And when I did go get him I turned on hall light, and said "good morning sunshine!!" and he gave me a big smile!
Progress, I guess? Will see how it goes tonight.
Thanks for your support.
