Kim, I've been following along and offer you many HUGS...My DS is not a great napper/sleeper either...
Now, I'm just spit balling, but with the state N is in right now, being so massively OT and teething, (and I'm going against all logical thought on this board
) but could you just abandon all ST right now and focus on getting him caught up on his sleep?
If he needs to sleep on you then so be it? ST, IMO, works so much better when they are not so OT. Maybe a CN in the car in the afternoon??? Again, just spit balling...
My DS will not go back to sleep either if he wakes after 4am...makes for a SUPER long day and when this has happened, we've had to have a 5pm bt - no other way around it...
Can you do a BT of 5pm for a few nights? N might just surprise you...
WRT the EBT, it did take my DS about a week to start to sleep in a bit longer. We still have some early mornings - it's all a work in progress...
HOw long have you tried the EBT's? Did you give it a full week?
Also, have you had him to the DR, just to rule out any other cause that might be bothering him?
I'm sorry you're having such a hard time...I've been there with the 4am WU and they SUCK...
Hopefully someone else will have some better ideas...
