I have 3 children , I have a 6 yr old daughter , a 3 yr old son and 3 yr old step daughter . Really needing help ? My daughter would have to be picked up from school . Pick my daughter up from school at 3 , be good to my babies , potty train , help with school work , I work a 2 , 2 , 3 schedule so I’m off every other weekend .
