Babysitter Needed for my Children - Full-time / Part-time

I am looking for someone who can watch after my 9-month-old baby boy when I have to work on weekends or a few hours during a week night. He is formula fed and is a very happy baby. He really likes to be jumping or standing and is very curious about everything around him right now. He also likes going for walks in his stroller. He takes one long nap a day and 2 or 3 short ones. He does go to daycare but I have to work some weekends and I need someone who will care and love for my baby when I cant be there.
