Hello parents of music students! Gary Marcus writes in his book “Guitar Zero” (The Science of Becoming Musical at Any Age):
“In studies of musical achievement, the one factor besides amount of practice that consistently predicts achievement is not whether you go to Suzuki school, or study under some other method, but parental support, presumably because most young children can’t apply themselves sufficiently without external motivation.”
So, I would recommend that you always encourage you child to practice on his or her instrument and praise them for their efforts and accomplishments.
