Similar situation for me too.

Me- bottle fed- UC pancolitis at age 15

My son- breast fed- UC pancolitis at age 20

My Husband- bottle fed- left sided UC at age 45

If there is any protection, it is not major.

Maybe it is the milk that is the problem and not the delivery method????

Shouldn't be. Mother's milk is in no way the same as formula, nobody is allergic to their own mother's milk (but could be intolerant of something mom ate!). So, it is not a different delivery method, but a completely different milk. All infants must have milk. The GI tract is not ready for anything else.

Both hubby's family and my sister-in-law's family could not breast feed or formula feed their 'male' babies. (yes, only the boys...Very strange). Hubby had 10-15 wet nurses the first 3 months of his life (wet nurses are women other than his own mother who have had babies and offer to breast feed yours if for some reason you cannot). He would tollerate the milk for a day or 2 then get sick and they had to change wet nurses. They gave up at 3 months and fed him bread dipped in sweet tea or sweet almond milk! That is about all he ate until he could start on real food. (Apparently a lot of babies from North African origin had the same problem. Complete lactose intollerence from birth.)
My nephews were allergic to all milk (Asian origin)including breast and after trying various formulas were fed rice or almond milk (soya didn't work either).
I've come across a lot of this in the North African population that I am surrounded with.
They are missing an essential enzyme.
All this to say that it happens but I do not know if it helps or hurts IBD or UC over the longterm.
