(((Hugs))) - developmental milestones and teeth can really mess with sleep. Have you medicated for teeth? Have you considered spending some A time in his crib so he can practice getting up and down again?
Generally if he stands in his crib, but isn't crying for you I would leave him to it. I know it can sound dreadful when they are crashing around in there and bumping into the bars, but he is unlikely to do himself any serious damage. If he did fall and hurt himself he would cry for you, and you would go to him. Obviously if he is standing and crying, then you would go to him, lie him back down (just the PD part of PUPD) and say your sleep phrase again.
Looking at your EASY I'm not sure what time you are aiming to start the day? Are you wanting roughly a 9am to 9pm day?
I do suspect he needs a bit more A time in general, though some of your A times are really long. Thursday for example he did 3h A time, then a great nap, but then he went for a nap only 2h later and slept 45mins - a classic UT nap. Then by BT he was way OT (probably already OT by 7.45pm) as he wouldn't have been able to handle a full A time after a short nap. Then today his day was way too long from 7am-9pm with only 2h of day sleep.
What I would suggest is aiming for a consistent 3h A time and two 1.5h-2h naps, so the day could look a bit like:
WU 9am
Nap 12-1.30/2pm
Nap 4.30/5-6/6.30pm
BT 9/9.30pm
If you get a short nap (less than 1.5h) then aim for a slightly shorter next A time, say 2h30-45. If one or both naps is short then I would bring BT earlier to compensate. If you get two good naps your day will need to be at least 12h long or you will get UT night wakings (cot parties!).
What do you think?
