A 3 year old should need to pee 4 times to 8 times a day or every 2 hours to 3 hours when they are properly hydrated.
The amount of times and how often the 3 year old will need to pee can also vary depending on their fluid intake and whether or not they are sweating or more active.
It's also normal for a 3 year old to have a different pattern and urinate or pee less frequently once they are beginning potty training.
The typical range for 3 year old's needing to pee is 4 to 8 times a day, which works out to peeing every 2 to 3 hours.
If the 3 year old has not had a wet diaper in 6 hours or they haven't peed in 6 hours, then they could be dehydrated.
The 3 year old may need to pee more often than 8 times a day if they are really drinking a lot of fluids.
For poop a 3 year old should poop as often as once a day.
However the actual amount of times that a 3 year old will poop can vary depending on the 3 year old's diet.
