Dogs identify, greet and show ownership through licking. I have one dog that licks everything in the house. If we bring something new in like the groceries they get licked. We get scared if it doesn't get the lick of approval from her.

Unless it is harming the kids I wouldn't worry about it. As stated above there mouths are cleaner than ours. If it is harming the kids then use some type of training technique associated with a command. They will always try to lick, but if you can stop them with a command you man be able to limit it.
