If you want her to get used to children, be sure to take her to parks where they have childrens playgrounds, and maybe to things like soccer fields where little kids are practicing, or schoolyards when kids are letting out of school. Puppies need to get used to kids running up to them and being noisy, even if you don't have any yourself. Make sure the kids approach her slow at first and have plenty of treats so they can give her little tiny bites .That way she will learn to associate them with wonderful yummy things, not just noise and commotion.
You don't want to have her be grown up and then panic when a kid comes running up to her unexpectedly some day. We don't have any little kids but once at a campground a boy came running up to Rocky and grabbed him by the head in a hug before I even knew what was happening. Luckily Rocky just froze there, and he had met little kids in our neighborhood so he wasn't totally unprepared for it. I still keep a bag of treats with me on a walk and whenever kids come by I have them give Rocky some treats just so he stays calm around kids, especially our very hyper little 3 year old neighbor boys!
