not being breastfed as a baby could be related with risk of a developing IBD?

Do you think it could be the origin of your IBD in some way?

In my case there is the circumstance that I was totally fed with formula milk during my baby life. More testimonials could be enlightening because I'm always wondering WHY?

On the other hand I know that this illness is very difficult to understand, and it frustates . So many advances in the world on techs etc, but many diseases are still not understood

Not the cause in my kiddos case
Both kids were exclusively breastfed - no formula at all
One kiddo has ibd - dx at age 7
Other kiddo doesn’t have ibd
My sisters two kids both had nothing but formula - no breast milk
Neither has ibd

So..It doesn't seem to have a relationship, contrary to what I have read in some studies.
You can't conclude anything at all based on three responses from random Crohn's patients on the internet. This is why they need to determine these things by running clinical studies - say a case/control study involving hundreds (maybe thousands) of people with and without Crohn's (cases and controls) that are matched with respect to age, sex, race, family wealth, and other demographic characteristics, and then you look to see if the rate of having been breast fed was statistically any different in the Crohn's group vs. the control group.

If it turns out that breast feeding is significantly less common in the Crohn's group, then it can be concluded that those two factors are "associated" with each other. It would not prove that breast feeding caused or prevented the Crohn's, only that Crohn's and breast feeding or not are associated.

To prove cause and effect you would need to start with bunch of newborn babies and have them randomly assigned to be breast fed or not and then follow both groups for decades to see whether the rate of Crohn's disease is any different. Of course that trial will never happen because it's too expensive, and scientists' careers are too short to carry on a single study for decades. Plus, very few mothers who otherwise wanted to breast feed would agree to forgo breast feeding their baby based on some hypothesis. Thus, we are stuck with the non-randomized, retrospective studies, that are usually riddled with error and confounding factors, that at best can show only "association."

Both of my IBD children were exclusively breastfed until about 6 months and then for about another 9 months along with solids.

When my first child was diagnosed I ran with the theory of 1/3 genetic 1/3 environment 1/3 trigger. Then my second child was diagnosed. Same location (albeit the most common site), same severity, same response, same outcome, same long term treatment. Over the years I have been very hard pushed not to believe in their case it is genetic and genetic alone.

My partner, their father, had a scope 2 days ago due to a 1in 3 postive FOB that they do for routine bowel cancer screening. We asked the GI to go the extra distance into the ileum. I have always been of the opinion that he had decidedly dodgy bowels but nothing that would equate to IBD outright or require further investigation on its own. Anyway preliminary findings are that he does indeed have Crohn’s.

Now try and convince me it’s not genetic. Lol
I am being surprised seeing that some of you have more than one child with Crohn's. I thought they were more isolated cases. My brother was recently diagnosed with SIBO

We were told siblings have a 33% risk of developing Crohn’s disease
Given my child started having GI issues at 14 days old -my bet is genetics
