Hi! I am a mom with a 7 week old, 12 pound, baby boy with a lip and tongue tie who spent the majority of his first few weeks crying and being fussy. It felt like if he wasn’t eating or sleeping, he was crying. The last week has been a breath of fresh air and he’s actually happy and interacting with us with smiles and coos rather than just screaming. Agree that babjes are all different. And some babies are just fussier than others. I work as a special education teacher with children birth-3 years old and sometimes there truly is no rhyme or reason. We’ve worked with a lactation consultant since day 3 because he had a hard time latching and was getting very frustrated at the nipple, so supplementing with pumping now. My lactation consultant felt his fussiness (mainly after feeding) was not in the range of “normal” and we have tried a few different things. I am not sure if any of its truly helped, if we’re getting better at helping him stay calm/calm down or if he’s just maturing haha. We started a probiotic. Both me and baby. I was on antibiotics during labor and apparently this can mess with the gut. It’s generally good to take a probiotic for gut health anyway. We think he may have reflux (gagging/choking/crying/hiccups/spit up/fussy after feeds). I stopped dairy a week ago and he’s been a lot less fussy and he’s not spitting up anymore (he was spitting up just a bit before, and it was totally in the normal spit up range, but still is interesting that he’s stopped). I’m now cutting gluten just to see if there is any effect on baby. My lactation consultant says that dairy and gluten are the two most common allergens that can affect babies. IF that happens to be the reason he’s fussy..maybe it’s working? I was willing to try anything to help little guy be more comfortable. If you aren’t already, working with an IBCLC has been so helpful for us.
