sure if they wanted it! how old is your kid?
I know a fairly famous musician that hails from Sweden who has beautiful dreadlocks that I believe are just as clean and well-kept as regular undreaded hair.
I guess if he wanted it. I saw a kid ,maybe 10, the other day with dreadlocks. I thought he looked pretty darn cute.
If their hair did it naturally then I would consider it. There are dredlock forums that have a lot of info on them.
Its a big commitment.
Ehh probably not.
