Tales of the Lost Diaper

Well, my little man is now 18 months old and counting! I can't believe how time has flown and the time I do have doesn't ever seem to be enough. Ever have so much housework to do that it's overwhelming so you just sit down? Yeah...that's been my week so far. However, the toilets are now clean..yah me!
I have also found the joys and addiction of Instagram...OH MY GOODNESS! It's a picture book for adults! Sometimes I wonder if I need to close all my social 'apps' and logoff....
Anyhoo....back to the world of toddlerdom. My crackhead little boy constantly digs in his crack and has now found out he can take his diaper off with or without clothes on. The other day, he wakes up and I notice he feels ... well..lighter and not so wet (let's face it..diapers do NOT work at night!) I lay him down on his changing table, pull his pants off and ... NO DIAPER!! What the crap?! I put on a new diaper, quickly pull his pants up and put him down. Then, I go looking for the diaper. I mean, it couldn't have gone THAT far, could it?! Amazingly enough, he didn't pee anywhere and I found the diaper between the wall and toys.
Then the other day, while I am at my desk, he comes running up to me laughing, then runs off...laughing more. As a mother of a 3rd child can tell you, things don't bother you quite so much anymore and you think, whatever. I continue to play, I mean work.
Then it hits me....did I see a flash of butt? He comes back, laughing harder and I see the peepee. AAHHH! How long has he been running around ... and where is the diaper?
Off a hunting I go. I look...and look...and crap a cow look. I finally found the sucker 30 minutes later underneath the kitchen table! I pick it up and little turds fall everywhere. All while, of course...he's laughing and running around trying to take his peepee off.
You know..sometimes I don't think there's enough Prozac for a day like that one. So, now all of my facebook friends are telling me...It's potty training time. WHAT? How can that be..he's only 18 months old! Doesn't he need to be at least 2 years old? They tell me no..it is time young mommawalker. How the heck do you potty train an 18 month old, stubborn, strong-willed little toddler who speaks in kid-latin?
One of my friends and future teacher of my little pooper, tells me her daughter was like that, so while at that time, she was a stay-at-home mom, she just took her pants and diaper off and let her roam the house. She would follow her with the potty chair and within a week, she was potty trained. Hmm...sounds easy I guess. However, we just got in new carpet!
Please! I need any and all help!
