In any case, with the semi- OK from our pediatrician, and the hope(!) that it would help MJ sleep longer at night, we gave it the ol' college try.
And after the first couple of tries, she seemed to really like it! And I don't know if it's just our imagination, but she is definitely sleeping in longer stretches now at night. She can pretty much go from 10pm - 8/9am with only one wake-up, usually around 2 or 3. Of course, this hasn't happened *every* night but we've started to notice a trend! Fingers crossed!
