Yes, these are fine for children of all ages. The only thing you need to do is show them how to use them properly and monitor their use. They should be slowly wiggled between the contact of the teeth (where the teeth come together, if they are touching) and then moved up and down on either side (both teeth) to remove the plaque from both teeth. The only other problem I see with these as opposed to regular floss is that the same small piece of floss is used throughout the mouth. This means that the plaque and bacteria are essentially being transfered around the mouth to each new area. So what I recommend (as a dental hygienist) is that in between areas the pick is rinsed or dipped in mouth rinse. I love these type of flossers for children or anyone that does not floss because of the hassle of regular floss. You don't HAVE to rinse the flosser, it's just something I recommend if/when possible.
