Pee Pee in the Potty.....not yet!!!!

Man, potty training has started at our house and much to my chagrin, it's going pretty much like Ethan's did.....I was hoping for a little better, but I guess we'll just have to continue to work on it.  As Ethan did, Colin will remove his underwear, and go on the floor....avoiding the potty as much as he can!  I time myself and try every 20 minutes to sit him on the potty and we sing, read books, play balls, etc and nothing is working.  The first couple of times it was great, he'd sit (well, he still sits) and tinkle, so I figured he understood what he was supposed to do, but apparently not!  Ethan, was almost 3 1/2 before he was fully trained, so I guess I have that going for me =)  LOL  It's like I sit him on the potty and try to keep him entertained, but no go....then the minute he gets off, it's like he's running for the nearest corner to pee in....I'm going to lose my mind, I think =)  As much as I love being a mother, I have to admit and say I hate potty training.....once we get over this hurdle, I know I'll breath a huge sigh of relief =)
