It is very common for children to get bit by a relative's dog. Dogs who have not been socialized (a lot) with young children are not quite sure of them. And, children that are very young my be unduly rough...I would say, your house, your rules. If you feel more comfortable having them locked away (rather than muzzled) then so be it.

The muzzle may make the dogs more nervous. I know socialization is important, but we had a hard time finding kids to socialize with on a regular basis. Most people don't just waltz their toddler up to a GSD at puplic places like parks so unless you have close neighbors or friends with kids it is hard to socialize them -and puppy hood flies by!
