Some people poop 3 times per day and some people only poop one time per day and some people only poop one time per week which is normal.
There's no set amount of times that a person should poop per day as some people poop everyday and some people go a few days without pooping and then some people go a week or even 2 weeks without pooping.
As long as you're pooping once a week or every 2 weeks then you're healthy and nothing is wrong.
The amount of times you need to poop per day or per week etc can depend on your diet and the more fiber you eat the more often you'll need to poop.
The less amount of fiber that you eat the less times you need to poop.
Some kids only poop every few days to once per week and some may need to poop more than once per day.
Everybody is different when it comes time to needing to poop.
