It is universally acknowledged by grown-ups that being a baby is mildly to moderately humiliating. You can't dress yourself, you can't feed yourself, you don't understand toilets; the list goes on.
And yet, when people have babies of their own, they swan about telling everyone about everything the baby ever does, no matter how embarrassing, with illustrative photographs. This is bad enough when they keep their audience limited to acquaintances.
But now, nutjob parents have an extra, simplified outlet for their madness! It is called the internet. They can post daily, with photos that they needn't even develop, and save themselves the trouble of actually speaking to people. The baby's words, toilet ability, height, and weight are relentlessly tabulated for everyone to see.
Now, it's probably true that few random people read particular baby blogs, and therefore the audience is not much changed. But there's that nebulous creepy internet publicity added, which somehow makes this whole thing more off-putting.
It is wonderful that you care that much about your baby. That is in fact to be preferred. But stop being creepy.
