When potty training a toddler the toddler should sit on the toilet for up to 5 minutes.
If the child has not went pee or poop in 5 minutes then they should be allowed off the toilet and not forced to sit on it any longer.
Then when you think the toddler is ready to pee or poop again you take then to the toilet and sit them on the potty for another 5 minutes.
Never get upset or punish your toddler when potty training as it will make it worse.
Sometimes a toddler will have a bowel movement or pee again once the diaper or pull up is back on which is normal because the diaper feels normal them.
Pull Ups do sometimes confuse potty training toddlers.
However some toddlers potty train just fine when wearing pull ups.
Pull Ups most often hinder potty training and confuse the child as a pull up feels like a diaper because it is.
Potty training a child is better using underwear so they feel wet.
For some toddlers pull ups can hinder potty training while for others pull ups can help potty training.
Pull Ups can feel like diapers because in reality pull ups are just pull on style diapers although they are less absorbent.
If a toddler is wearing pull ups and pees in them then they won't feel wet like they would when wearing underwear.
Just like a diaper the pull up absorbs the pee and so the toddler does not feel wet.
