Behind every super mom, there's an ant lifting 10 times its weight! Just ask January Jones!
The Mad Men star was spotted taking her baby Xander to the store, with the help of her little sister Jacey Jones!
Ch-ch-check out the pics (below) to see just how much Jacey helped when January had to take a business call or two!
Hey, you ever notice that baby sister is only one letter off from baby sitter? Hmm, funny…
Well, we've got to go film our hit TV show! Later!
