My DD was put on similac neosure by the NICU and ever since we switched she's seemed to have a hard time passing stools and is constantly fussing, bearing down and grunting with no success. I had read that it causes tummy trouble and so we switched to enfamil enfacare and so far, we've had two bottles on it and no problems! Well see if it's coincidence or if it's related!
