Hi, FTM of 4 month old that has been having GI issues as early as 6 weeks. Trying to find the best way to summarize this whole journey because it has been a ride!
We have gone through multiple formulas and have concluded LO likely has CMPA but now I’m thinking MSPI? He often has mucousy stool and occasionally has streaks of blood. He also has crazy gas that is often painful and disrupts his sleeping at night. He is already a poor sleeper(maybe reflux?), i am lucky if he gets a 3 hour stretch at night. I am combo feeding and have been off diary since 7 weeks old. After trying goat milk formula for about a month with no relief, we switched to HA Similac Alimentum. We didn’t notice a drastic change but thought sticking with it might make a difference. Well starting last week, I’m noticing blood in his stool again. I also made an apt with a GI and got an appointment for 5 months from now! Our doctor hasn’t been so concerned as we have a big boy and all this hasn’t impacted his ability to gain weight. However, he is in pain often from gas or pooping and I’m also worried he’s not getting enough sleep. Plus, it’s never comfortable opening a diaper and seeing blood.
I’m wondering what other people have experienced and what my next steps should be. I am starting to cut soy now too but I noticed the Alimentum is made up of 1% soy. Should we be pointing to my breast milk or should I be changing formulas again?
Please let me know if I can make this more clear!
