Rachel Farrar’s 19-month-old son, Daniel, is sleeping much better today, but that was not the case about a year ago when she became a participant in a U of C study, reports CBC.

If you have a five-month-old baby, sleep might be a rare luxury in your home, and Rachel Farrar knows that all too well.

“He would sleep for about 20 minutes, which I thought was normal. It turns out 20-minute naps aren’t so normal,” Farrar said of her sleep struggles with her son, Daniel.
