Potty training woes

I think I am just getting to old for this business or my patience isn't what they used to be.  Hmm, I think patience and age go hand in hand.  I don't want to get OLD!  Zack is 12 and potty trained by 2 yrs and 3 months.  This included night times as well.  Logan was potty trained by 2 yrs and 6 months this too included night time.  Now Isaiah is another story. Right now he is 2 yrs and 8 months and has just started to want to have something to do with the toilet or the potty chair.  

We have an elmo potty chair that speaks in English and Spanish.  I suppose it is for those that want a bilingual potty broke child. (I just need the potty broke part)  It is cute and hey when the kid does the deed it congratulates in either language.  Isaiah stood there looked at him and walked off.  He prefers to go naked.  No diaper, no underwear.  I even got him some cute big boy undies, and he cried.  I think he knows he is the baby and it breaks my heart that he is growing up so fast.  On the other hand, I would like to save some money on pull ups!

The other day he was doing really well with the potty business then he decides to take a poo on his jacket.  I had some winter coats that I had to wash lying on my treadmill to hang up.  I was getting ready to hang them, but first I wanted to check my e mails.  All the sudden I got a whiff of some nasty poo smell.  I saw the cat go to the cat box, but this smell was like under my nose.  I checked my feet, I checked Isaiah's  feet, then I turned and saw the deed.  Why?  Why did he choose the jacket?  If he were a bull I would understand since the jacket was RED, but for the life of me I have no answer.  He thought it was  punny aka funny!  It punny mommy.  Then he laughed.  I didn't.  I gave him my evil look, and said you do NOT poo on the jacket, you poo in your potty.  He just looked at me and walked off.  Phew!  I gave up and sent him to bed, of course he had a pull up on!
