Having trouble getting a baby to nap during the day? First, wear them out by letting them play for 60-90 minutes. Then, put them in your lap and play Beatles music, singing along softly. After about 15 minutes, cue up “Hey Jude.” Guaranteed, but the extended fade-out, your child will be nodding off. I’ve always been a Lennon guy, but I will give McCartney credit for once.
