Some children show a preference for either the potty or the toilet whereas some are happy to switch between the two. A potty can be more convenient, especially when you start going out and about, however getting used to the toilet is important as that is the ultimate potty training routine. For some children, especially those who find learning new routines difficult, introducing the intermediary stage of the potty can be confusing.
The most important thing is that your child is comfortable enough to sit on there for sufficient time to do a wee or a poo. In both cases some toys or books can help keep them there for longer.
If using a potty, it’s a good idea to show your child that wee and poo then goes down the loo, and that the next stage is to flush the loo.
Toilets can sometimes scare children, because of the drop. A piece of kitchen paper over the drop can help with this.
It’s really up to you and your child to decide which option works best for you.
