Re: @palpy: Yup. Quite bullshitty.
"Personally I can't really see the point of taking pictures of your kids in the bath unless you're planning to embarrass them when they get older but some people seem to do it."
A parent (such as I am) doesn't do that because there's a "point" to it, or to embarrass them at a later date (though that is something that you will almost certainly do). We do it because we love our kids and take every opportunity to take photos of them whenever we can, and in whatever situation.
Bath-time is one of the most enjoyable times for both parent and child, and there's few things cuter than your kid grinning up at you from a mass of soap-suds.
