All mothers are legally bound do this. It is built into us although some of us have learned to hold in the desire to the point that we can go to dinner parties with adult friends and only bring up the kids only 647 times instead of dominating the conversation with anecdotes of toddler doings.
Blogs of Stay-at-home moms tend to exhibit this phenomenon to the extreme, mine included. This is completely normal and happens to be the reason that the readership dwindles to about two people (Daddy and Grandma). Because I want to build my readership to 44,000 daily, I am not bragging in the least, tiniest way when I say I have a special video of an incredibly cute little guy who, in my completely unbiased opinion, is a genius. He's putting together a puzzle that I even have trouble with since every single little car shape looks exactly the same as every other one. But this kid, who can't even use the toilet yet can put this thing together like a pro. I think he's going to get a really important, high-paying job someday, like wooden puzzle tester. But I'm not bragging.
So enjoy this video and if you think your kid is cuter or smarter than this, I'll come over to your house and beat you up. Okay, just kidding, I don't brag. Enjoy!
