Kids and potty training

My oldest was difficult. She refused and refused then one day she started going on the potty here and there and then it got to be all the time & consistant. Some of that started getting better once she got into speech therapy & like your child saw others doing it and wanted to join in.
My middle she did it on her own, she was done right before her 2nd b-day. She was super easy, she saw the potty sat on it, praised her alot and cheered when we went to go dump our potty & flush (I did that too w/ my oldest).
The lil guy well he just turned 2 & will go on the potty as long as he's bare bottomed but doesn't always "go" but it's still a start. He wanted me to help him get his diaper off after he did #2, wich is a lil sign he doesn't like wet or icky on his bum anymore either.... baby steps! I'm hoping to be done by 3 or at latest 4 as they say boys take longer.
