Toddlers don't usually use as many diapers per day as they used to as a newborn or younger baby.
As newborns they would usually go through around 10 to 12 diapers per day but as they get older they tend to pee less and less often.
Most toddlers such as 1 year old or under 2 years old go through between 4 to 6 diapers per day.
Then if they're still in diapers between the ages of 2 to 4 years old they may only use between 3 to 5 diapers per day.
All toddlers are different but as they get older they'll use less diapers per day but most toddlers after 2 years old use between 4 to 5 diapers per day.
Because the toddler tends to hold the pee in and then lets it out all at once at certain times.
