SOME ADVICE
A good way to share photos of your kids with people you trust using facebook is to upload pictures of your kids to a specific album, then adjust privacy settings of that album so it can only bee seen by a specific network you are in or by anyone you specify.
You may want to set up a network of just people you want to see those pictures.
That way you can post a ton of pics of your kids that your family can see, but the rest of your friends wont have to see your kids faces covered in ice cream or washing the family pet in their feed every 20 mins...
