Hi J.,
Congratulations on your growing family :O)
For my son, I used the potty seat that fit on top of the potty. I just removed the "peepee guard". I did this originally for easier cleaning. I was even able to travel with it to Auntie's house, a tailgate, etc.... and be abel to remain consistent because it traveled well.
I did have to have a small step-stool for my son to get on/off eaiser. I was trying to teach him to NOT need my help at all.
I remember a friend of mine long ago (before motherhood), and she had her sons sit on the potty facing backwards. They never used a potty seat. I can see why she did it, because it does work.
Anyway, I hope that helps you :O)
