[Gender difference in music therapy]
Young women hummed Brahms' lullaby over and over to some premature babies, but not to others. Overall, the babies who had women humming to them were discharged an average of six days earlier than the babies who didn't. This time, the gender difference in the results was even larger. Premature girl babies who were hummed to {??} left the hospital twelve days earlier on average than girl babies who weren't. But premature boy babies who were hummed to {??} didn't leave the hospital any earlier than boy babies who weren't. Why the difference? Why did music therapy work so well for the girls, and not at all for the boys? The most plausible explanation is simply that boy babies don't hear music as well, or in the same way that girl babies do.
I think the word followed by to is dropped. I think it might be " sleep" but I am not sure. What is this?
Is it correct grammatically?
