Well, today is day two... He's alert, peeing tons, eating fine...
When do I worry?
Many EBF babies go 5-7 days without a poop. VERY common. Both my older DD and now this little DS are like this. As long as he's not showing signs of distress, gassy, uncomfy, very irratible, etc. you're totally fine.
When he does poop - it should be the same texture, consistency, color, etc that you're used to - and pretty big in volume! Pretty much every time DS poops we can count on a soiled outfit. But since it only happens once a week, it's not so bad.
Not to worry at all. My Dr doesn't worry about anything less than a week. And even 10 days if everything else is good isn't necessarily cause for worry. But if you're still in the smallest size of diapers, I'd be ready to go up a size. You're in for "up the but and out the back" in my experience - LOL!
Oh, I am so relieved to find this thread! My EBF one month old daughter is on day 2 without pooping too! She had started going down to 1-2 x/day earlier this week and then just stopped. Everything else with her seems fine! She's eating, peeing a lot, sleeping well at night (I know - crazy) and is alert during her wakeful times. She does get gassy but she was gassy even before the "poop strike" and it's not like it makes her scream or anything... she doesn't seem to be straining or anything either. I am going to wait a few days before I start getting stressed by this! Thanks for the info!
