Okay guys my little man is 3 1/2 months. We ebf the first 2 months and then started slowly adding formula for during the day while I’m at work. I still nurse in the am and before bed. He was on similac pro advance the one similar to breast milk but his poops got super super loose and watery so I called the dr and they had me switch to pro sensitive. His poops are now the consistency of warm syrup and gargantuan amounts. Like every diaper is horrifying 🤣 but the last 2 days he started straining when he poops. He’s not fussy but he’s trying really really hard and putting his whole body into it, it’s kind of cute because he grunts at the same time but His poop is still that syrupy consistency so I don’t think he’s constipated he’s just acting like he is. He also has been up all night farting for the past week. He’s been on this formula for about a week and a half now. I’m just wondering if this is all normal the straining and the syrupy poop or if I should contact his pediatrician again for another formula switch?
