The age at which most toddlers wear size 6 diapers is 2 and 1/2 to 3 years old although some toddlers wear size 6 diapers at 3 years old to 4 years old.
Size 7 diapers kids of 4 to 8 years old wear size 7 and size 8 diapers.
Toddlers usually need a diaper change every 2 to 3 hours in the day.
Some older toddlers may only need a diaper change every 4 to 6 hours depending on how much they pee.
How often you should change your toddlers pamper in a day or diaper in a day depends on the toddlers age and how much and how often they pee and poop.
With pee a toddler needs a diaper change on average of every 2 to 3 hours although some toddlers may go as long as 4 hours before needing a diaper change.
If the toddler poops then give them at least 10 to 15 minutes to finish and then change the diaper.
For pee the diaper can fill up with pee before changing it as the diaper absorbs the pee and locks it away from the toddlers skin.
You should check your toddlers pamper or diaper every 1 hour to 2 hours and change as needed.
2 year olds use around 5 diapers per day although some days the 2 year old may only use 3 to 4 depending on how much they drink and how often they pee and poop.
2 year olds usually need a diaper change every 3 to 4 hours and at age 3 they usually need a diaper change every 3 to 4 hours.
As the kid gets older they tend to use less diapers.
A 2 year old uses on average of 3 to 5 diapers per day.
Although some 2 year olds may use 6 to 7 diapers per day depending on how much they drink and how much they wet.
My kids when they were 2 years old would use 3 and sometimes 4 diapers per day and as they got older sometimes they would only use 2 to 3 diapers per day.
As long as your 2 year old is having at least a few wet diapers per day then they are hydrated and healthy.
Diaper changes are usually needed every few hours and sometimes only ever 3 to 4 hours.
The more the toddler drinks the more they will need to wet and if they poop then they should be changed after about 10 minutes of noticing it.
However if the 2 year old is sleeping and they poop and it's not bothering them or waking them up then it's safe to leave the 2 year old in the poop diaper overnight.
