Yep. I mean poop. Curious... My son poops at the same time, every day. Like clockwork. Comes home, backpack down and makes the announcement like he's 80 years old "if anyone's gotta use the bathroom I suggest you do that now, I gotta take a load off"
He's 9. Lol.
Anybody else's child poop on schedule? Lord knows I wish I did.
Obviously my child does not poop like clockwork like that.. he just poops a lot :)
But from personal experience.. before I got pregnant, I was like clockwork too - just like your son.. I knew exactly when! lol
