Mother came complaining the following history

Child, 10 Months, Female

Mother came complaining the following history:

Since when the child started to crawl, at age 6months (4M ago), she is unable to move de left limb, or do it difficultly. The crawl is as shown in the video.

Normal delivery, no known history of thrauma.

O.E, no swelling, no pain on palpations.

I need help!

Case from Mozambique

Not every child would crawl the way we are used to. some would shuffle. Some would not even crawl at all and move on to walk at the right age. This child looks perfectly normal to me.
