If a baby felt down in 3 feet of height what need to be checked at first

A. First you have to check on which side your child had fallen was it head or the legs of the child so whichever side the child had fallen first immediately checked that place because 3 feet is a good height for the child with a child can actually get hurt on whatever side your child had fallen check that in immediately please go ahead with consulting the doctor if you see any swelling or dent in that area
