For potty training that is!;)

I used underwear, so I wouldn't have to go back and teach them to pull their pants down to go potty.

They learned everything at once, including night-training!

We are doing it with bare butt because anything on his butt he will just go in the bottoms and refuse to use the toilet.

I think using undies helped my girls understand they are wetting themselves when they go. I let them go nakey a lot too though cause it was easier for them to make it.

When I was potty training my oldest I noticed he always had accidents when he wore undies. I think it made him feel like he was still wearing diapers/pullups.
