14 months here with Emilio and he's begun them too. I'm quite certain it's seperation anxiety. He cries hard now for his nap too, even when he's literally exhausted. However, he will lie right down and go to sleep with my hand on his back. Tracy says to ride these sep. anxiety phases out WITH the child. Very important. By leaving them to cry (just an fyi, not saying you are!!) you actually *increase and validate* their anxiety. So, I'm settting up camp next to Emilio's crib tonight as needed.
Now, I suspect we have some eyeteeth bothering him too, so I'm giving him a shot of Motrin before *I* go to bed to maximize its effectiveness while I'm alseep. I wake him a bit to give it to him.
True sep. anxiety will last a week or two if met lovingly and reassuringly and whilst not introducing new props. BTW, I try not to pick Emilio up, just lay him down gently, offer him his blankie, tell him 'suck, suck, suck', his cue to suck his thumb and ride it out with him.
He shares a room with Diego, who interestingly enough sleeps through most of it!
*yawn* I'm tired today though.
Florencia, they don't forget how to sleep independently ... don't worry, just gotta ride this one out. There's often a huge sep. anxiety period when they start walking. It's like the last tie to Mama being broken and is actually both thrilling for them, and very frightening in ways they don't understand.
