Potty chair.
I used the baby Bjorn. Great.
The thing with a potty chair is... convenience, and it is approachable by a young child. You can place it anywhere, where the child is, to get them used to seeing it... and adapting to it.
Then also, a child initially cannot "hold" the pee too long, before going all the way to the bathroom toilet... so they can have accidents. But with a potty chair, you can place it right next to/near them, where every they are, and it is easy to get to.
Both my kids have used it, to great success.
Then, when they have attained mastery over their biological cues and bladder... then you segue them to the toilet. Its not hard.
When they are "ready" they will be ready.
Remember, it is about taking steps... a process... not all expectations will be met at one time. One step at a time.
Potty training is in steps:
1) pee ability in the potty and the ability to "tell" you they have to go. Then mastery of that, consistently.
2) Pooping ability, in a potty and same as above.
3) Being able to "hold" it long enough to get to the toilet.
4) learning how to "wipe" themselves and having the maturity and motor coordination to do it, by themselves, well.
5) Night-time dryness/dryness during naps-.. which will not be attained at the same time as daytime potty training... and night time/nap dryness is biological based... and also has to do with the myelin nerve sheath development as well. Night-time dryness "ability" will not occur until even 7-10 years old sometimes. And this is normal.
6) Accidents will still happen... even if potty proficient. So its okay. Its normal.
7) ultimately, if a child is "ready" for potty training, it will be less of a battle and a torture for them. If the child is not "ready", it will take longer.
8) punishments/forcing them... will not help.
A GREAT thing to have.. .is a car potty. You can get it at like Amazon, putting in the search words "on the go potty." THIS has been a lifesaver for our family, and my friends... when the child has to pee and you are on the road or stuck in traffic and there is no bathroom in sight, nor can you get to a public bathroom fast enough
All the best,
