My son is starting to show signs of wanting to use the potty so I brought out the potty we bought for him awhile back.  What my boyfriend and I noticed is that when he sits on it it tips forward and it causes him to dislike the potty and he becomes a bit scared to sit down in case he might fall.  What my advice to you is when you are purchasing the potty is to make sure it sturdy enough for you child.  The pottys taht are made to look like a realy towlet are not very good because they are thicker on the top then the bottom like a regular towlet, which is ok  because it is cemented to the floor.  Since my son doesn't like old potty we bought him, we went out and bought him a new one.  This potty doesn't tip and it somes with sound.  It has the handle to flush and tolet paper roll that spins and it makes music.  It sings really cute encouraging songs.  It says up and down/open and close when you lift the towlet seat, which is good for the boys for when they get older there are gonna have to put the seat down for mom.  Here is a picture of the potty for you all.  Happy potty training to you all.
