Is it leagle to babysit without a license and be 13?

I started babysitting a 6 month old baby when I was 13, but I was under supervision for the first 3 months. Then six months later I was watching two infants at a time every now and then because the mother of the baby I was watching told other parents how good I was watching her baby.

So, a 13 year old can babysit, but I suggest starting off with babysitting one child at a time with supervision until an adult feels comfortable leaving the 13 year old unsupervised. They must be disciplined, responsible, and mature enough to be able to care for another child especially infants and toddlers.
