We are literally at our wits end with this. My poor boy has had trouble passing stool since I stopped breast feeding when he was 2 weeks. He's now 3 months. We've had various trips to the dr with no help realy at all. We've changed his milk a few times and now on nutrimigen which he doesn't like the taste of but still after 2 weeks on the new formula no change and he doesn't poo without our help. We have to use windies and suppositories to help him go. The pain he gets in straining is awful to watch. I just don't know what else to try so any advice or if anyone has had the same problem please let me know.
