Suspected CMPA?

[Elliehowells]

My son is now six weeks old and at 2 weeks | found blood in his poo. Went straight to GP and they suspected it was a dairy intolerance.
I then went straight onto a dairy and soya free diet (instructed by the GP). However the following morning I wasn't happy with how my son was being, very agitated and upset and seemed like he was in discomfort in his tummy, so we went up to our hospital's paediatric centre on emergency. Again, after having his observations and weight checks, and listening to his symptoms, they also put it down to 'suspected' cows milks intolerance.
May I add, the only symptom my son is experiencing is blood in his poo. None of the main symptoms of CMP1, but this is what it was put down to. I was told to wait 4 weeks to give the dairy in his system time to pass and was told the blood would decrease and eventually have none at all 4 days after.
Fast forward to 4 weeks later (1st July) he still has blood in his poo and I was again told by paediatrician that it was CMP1, and as sure this woman was, she still wouldn't diagnose him and help me maintain a healthy diet to get my son on the right track dairy free. I have been back to my GP today on the 2nd July (however I saw a different doctor to the first appointment) and she is pretty certain it is NOT dairy/ cows milk intolerance (CMPI) as the blood in his poo would've gone by now, even with the slight possibility that a food that I may have digested that may have contained a dairy product could ve gone into his system. It would pass within 24 hours.

I have been so careful with what I've been eating to ensure I'm not having anything with any dairy or soya product in to the point l've lost weight because I'm scared to eat anything and thus have weakened my breast milk supply as a result of this.

Might I add, my son has had no rash or eczema, no projectile or discoloured vomiting, sleeps from 11 pm straight through to 6 am, loves his food and has been gaining weight since he was born. He was born 8lbs goz on the 19th May, he is now 11lbs 14oz today (2nd July) and ONLY drinks breast milk.

Please can any other mother relate to this and help me get on the right path of other possibilities that could be causing the blood in his stool.

My daughter has multiple allergies so it still could be foods in your diet. In total she has 20 food allergies. Every time I cut a food out I ended up replacing it with a different food she was also allergic too. She has delayed allergies which are sometimes referred to as intolerances. At diagnosis her symptom was only screaming now her main symptom is loose stools and only as a toddler has she developed a rash. She does have reflux too but this is in addition to allergies rather than caused by allergies. She has never had issues with weight gain

If you are still getting blood I would think it means there's something else in your diet that is causing issues. Egg and gluten would probably be the things to look at first. If you don't want to do a full exclusion of each you could remove for 1-2 weeks then eat a lot of egg /gluten and see if the blood gets better then worse.
