Do parents take their children on Hajj, or are Muslims instructed to go on Hajj as adults?

Parents are allowed to bring their children along for the sake of convenience, but it is not encouraged because it is believed to be distracting for the parent to be at constant alert of their child's safety. Also, the Hajj would not be accounted as a deed towards child because every individual is expected to make their journey to Mecca with their own earned/accumulated money. The traditional way is to make Hajj when one is married and can afford to go with their spouse.
