Can an 11 year old take care of a 10 year old brother 6 year old sister and a 5 year old brother?

HI! I am also 11 year old. Well, you obviously can't take care of a 10 year old brother but you can take care of a 6 year old and 5 year old. Its a bit hard but if they are calm enough, its easy as a pie!! Good luck and hope they wont get too naughty!
