hello all, my baby boy 4 months old..whenever he folds and releases his legs some clicking sound can be heard from the knee joints..what may be the reason?how to reduce it?please reply

Hi Amrutha, It is very normal in babies. These sounds are perhaps caused by sliding tendons, which happen when soft tissue (tendons) interacts with hard tissue (bones). But get it checked by the doctor if your baby makes these sounds in her hips, particularly if they are a clunking, rather than clicking. Else, it is normal.
