Baby didn’t poop all day

Hey, ladies.

My baby has had consistent dirty diapers since she was born. Yesterday she pooped A LOT, but today, she didn’t poop at all, even though she is nursing frequently. She isn’t showing any signs of discomfort or gas. I’ve read that this is normal at three months, but, if she doesn’t poop by tomorrow morning, I will call my pediatrician.

Has this happened to anyone? Did you do anything to help?
