CONSTIPATION

WHEN MY BABY WAS BORN I WAS SUPPLEMENTING AND breastfeeding..THE HOSPITAL GAVE ME SIMILAC ADVANCE NON GMO TO FEED HER BECAUSE SHE WOULDN'T LATCH ON..SO THEY TOLD ME TO pump AS WELL. I DID THAT AND SHE WAS POOPING FAITHFULLY FOR THE FIRST WEEK IN A HALF AFTER EVERY FEEDING. AFTER THAT WE GOT HER ON REGULAR SIMILAC ADVANCE AND I'VE NOTICED SHE'S BEEN REAL FUSSY AND COLICKY..SHE STRAINS REAL BAD..SO THE DAY BEFORE YESTERDAY I WENT TO THE ER THEY SAID IT'S NORMAL.. I CHANGED HER FORMULA TO SIMILAC SENSITIVE AND SHE FINALLY POOPED LASTNIGHT BUT SHES STILL STRAINING AND CONSTIPATED LIKE SHE HAS MORE IN HER..IDK WHAT TO DO?? I'VE TRIED PUTTING A QTIP IN HER BUT THAT DIDN'T HELP💔💔💔 I'M JUST REAL WORRIED I'M A FTM WHAT CAN I DO TO HELP HER??
