The tags and whether to keep separate or merge was discussed in the general tag issues thread but not many people bothered to comment on it at the time.
I was just "being bold" since the few votes seemed to think it was a good idea to lump them together but certainly feel free to discuss and change them. I think Dori did the original merging and then I added more to my answer later.
One problem might be where the family fits in if putting children of different ages in different tags?
