Stress? Or something else?

[goodtimes]

My new 4 year old poos an awful lot when in the school.
I lunged him today for around 20 mins and he did 3 droppings. All normal looking. He often does this when in the school.

Is this excessive? My last 2 horses didn't poo as much.

Am I just worrying too much?

Probably just stress, you don't want to be behind my 5yr old when we go hacking. 12-15 in the hour is standard (observed by a slightly odd child I was accompanying!)
