Can your friend help you baby- sit even though she does not have a license but she has experince?
He or She may help you baby-sit, if the parents say it's ok. BUT the parents say it's not ok, she can not help out because sometimes you don't know what your friend is going to do at any time because if you tell the friend you are going to take a shower (which I doubt you will) but if you are, she may not want to stay because she knows you are and they want to go somewhere else or the baby's crying is just make her made like crazy. SO if I was you make the right choice, but if you need some help, just ask a friend that you know and trust REALLY WELL!!!!!!!!!!!!!!!!!!!!!!
