There are differences between the potty, the potty seat and the toilet. The potty method is preferred by many parents. It's portable, and it's the right size for little ones. The down side is that it needs to be cleaned after every use. It can be good for teaching children about cleanliness and personal hygiene.
Some parents prefer to skip the potty stage.
There are potty seats that can be attached to the toilet or you may choose to go straight on the toilet. The toilet is available with running water, and less chances of accidents and spills. To alleviate fear, you can show your child to sit facing towards the wall. Your child will be able to get on and off with more security. Accident are inevitable no matter which method you choose.
