My daughter had this i guess, she couldn't poop on her own. and at 4 days old, screamed all night until we got her to the ped's office who inserted a thermometer and poof, she pooped and all was good in her world again. I kept a log of her feedings and when she began to go too long and she would get fussy, then i would insert a glycerin suppository and poof that was all she needed to help her go. We continued this for awhile (3 months)and it got old, but she did evenutally figure it all out and we haven't had any problems since. She does tend to be constipated so we make sure she gets plenty of water and fiber in her diet. i remember being so sleep deprived and husband & I got up at like 2-3 in the morning to help her poo and we heard a little clink noise and hubby asked me ehat it was, but I snapped at him and told him i couldn't multi tasked at that hour and that I would deal with whatever it was tomorrow. Well what it turned out to be was my wedding ring that fell into the dirty diaper and went into the diaper pail which was dumped that morning and taken to the dump!!! there went $5,000!! So now I have a great story to tell, but not sure it was worth the cost, LOL. Worst part was we had been married for ten years and i had just gotten the ring made as my hubby upgraded my ring after ten years and i had barely had it 6 weeks!! Anyway, I know how horrible it is to not know how to help them and what is wrong. Best of luck and hope you get answers soon.
