Poo...none for 12 days

Yes, we were real puzzled why Keren didn't poo for that many days. We decided to call the doc to check on her. She is on breast milk most times aside from the few feeds of formula for nights (at most 3-4 times in all). So it cant be constipation. Who knows, she finally did it after her morning feed. It was a diaper full of soft poo. She must be trying to avoid the doc.
