DD is EBF and hasn't pooped in 4 days. She's straining to go and now has the rankest adult smelling gas so I know she's constipated. I bought some apple prune juice this morning. She's never had anything but breast milk. Do I just dilute it with water or add it to breast milk?
ETA we've never had this problem before and I've already tried the rectal thermometer and qtip tricks but without success.
