We are doing the potty training thing right now. We started in October and by Christmas, Monster Man was fully day time trained and I started to feel comfortable taking him places, then he woke up one morning and refused to wear underwear and use the potty. So, we had to start over from the begining.
Now he uses the potty and very rarely has accidents - as long as he is naked. Put him in underwear and he wont go!
So for the sake of less diapers to change, there is always a naked Monster Man running around. Hopefully we can get the underwear thing down soon so we can be completely diaper free again... Oh a mom can dream!
