If you measure people's thoughts, rather than asking them about their feelings, it seems they really enjoy the time they spend with their kids. Here is an excerpt from BPS Research Digest:
In terms of pleasure, the results confirmed earlier findings,
suggesting that we spend an awful lot of time doing things we don't
find pleasurable, including "work" and "shopping". Out of 18 key
activities, "time with children" and "sex" both came in around
mid-table, far below "outdoor activities" and "watching TV". However,
consideration of the ratings for "reward" (as opposed to pleasure) told
a rather different story, with "work" now the top scorer, and "time
with children" not far behind.
Commuting, however, cannot be saved by a similar move.
