My 10 week old came out nursing like a champ; could hardly get her to take a bottle once a day. She also pooped 2-3 times/days. Week before she turned 2 months, she stared having poopy issues; now only goes once every 5-7 days and she's been a super fussy eater since then and REALLY gets fussy when attempting to nurse her. Much to my dismay, have given her prune juice a few times per her Dr. It worked once or twice but not since. I am so sad and frustrated! Anyone out there w the same issue?
