#AskTheExpert my babu is 6 mnths old but while playing wid him or picking him up the sound comes from his bones cracking sound or griding sound is it normal or should i go to doc

A. Those sounds are probably caused by sliding tendons, which happen when soft tissue (tendons) interacts with hard tissue (bones). It's very common for a baby or toddler to make clicking and popping noises—similar to the sound of cracking one's knuckles—in the spine and around the shoulders, knees and ankles.
