Yes Cavoodles do make good family dogs and they are pretty good around children.
However if you have a Cavoodle you should teach your kids to play gently with the dog because some children may see them as toys which they are not and may agitate them to where they could bite the child.
But as long as the child plays nicely with the Cavoodle dog then the dog will treat the child and family nice and they are loving dogs.
They are pretty playful dogs but if you do not treat them properly then they could become aggressive towards you or your children.
My neighbor has a Cavoodle and it's great with her kids and it's very cute dog and pretty easy to take care of.
