Lo's are 18 months. I started working on the 1 nap transition very slowly back in Nov. we then went away for thanksgiving and when we came back they started magically sleeping later which allowed me to transition easily to 1 afternoon nap. That was short lived and must have been just catching up on sleep bc they're back to waking at their normal time again (around 730 for b and 800 for a). Problem is, they can barely make it to their afternoon nap now but if I put them down in the morning, they won't go back to sleep in the afternoon, and if they do it wouldn't be until around 5 which completely messes up bedtime....so I'm trying to stick to the 1 nap and have just moved it up to 12:15, immediately after lunch (if I make it any earlier, they are too tired in the afternoon leg). The real problem is the past few days it appears that they're overtired and are napping terribly (today not at all....yay!). I feel like im stuck between a rock and a hard place with this. Has anyone had any experience with this and words of wisdom?! TIA.

Re: Nap time help- the 1 nap transition
Mine went through a different sleep transition a couple weeks ago where they started playing and talking together instead of napping. I had to move one crib to the other side of the room and that fixed it again.
Good luck! If you haven't read that book, I swear by it. Mine sleep tons better, not perfectly yet but I'm not super rigid about STing (and my boys just turned 19 months)
