Photoview (self-hosted web app) does a pretty good job to group pictures by faces. It first self-detects similar faces and then lets you merge these groups together. New pictures then get directly assigned to these groups. For kids, I usually had pretty large self-detected groups, e.g. years <1; 1-2, 1-7; 7>. The most mismatched group was baby pictures (<1 years old kids).
