Isn't helping our kids recover from an illness just so fun??
We've all been here, as you've probably seen from recent posts! With my son, we go cold turkey. We wait until he's clearly 100% better, and then we let him cry. It's surprisingly quick, how he gets back on track! And remember that you can choose your own take on "cry it out." You probably didn't leave your son to cry for hours, when he was first learning to soothe himself to sleep. You listened, you decided, and you acted based on your own experiences. And it worked, right?
Of course that nighttime soothing during his illness was so nice (and necessary!), and of course your son would love to keep getting it! But it's ok to remind him that he knows how to soothe himself. :) Whatever you did before, to help him sleep through the night- do it again! And be very consistent. If you don't make a choice and keep to it, he'll cry longer and harder (in hopes that you'll change your mind). Get that good bedtime routine going, leave him a sippy cup of water in his crib, and be ready to hug your hubby a lot. In a couple of days, he'll figure it out!
Glad everyone's better now!
