What causes joints to make snapping, popping noises? Q: I am a 20-year-old in okay shape and health, but the joints in my upper and lower back and shoulders are always stiff and snap all the time. Are noisy joints the sign of some problem? A: Snapping and popping of joints is common.

Between about 29 weeks and 33 weeks your baby starts to make out high-pitched sounds too, such as a child's cry or a car alarm. You may be able to tell if your baby can hear sounds outside your womb (uterus) by playing music, and reading or talking to him. If he can hear what's going on, he may respond by moving around more. Studies of newborn behaviour show that babies get used to the music and voices they've heard in the womb.
