Yes, it all depends on the child. If the child can't sit still, I would advise the parent to assist in calming and positioning the child. I always like to introduce the clipper to the child and let the child touch and hold the clipper before I start cutting with it. When dealing with infants like 2 years old or under, I usually tell the parents I can use clippers on them but only 2 guard and up. Any clipper guard or lower blade will be to hard to blend if the child doesn't sit still and usually the end results don't look good.
