How long for soy to leave breast milk?

[BabyAllergy101]

My six month old breastfed baby was always sicky with bad nappies. I started to combi feed her at 4 months with formula but that caused green mucous poos so I stopped and also cut dairy out of my diet about six weeks ago.

This last week she's had horrendous trapped wind overnight, up for an hour or two in pain, and then passes loads of gas and usually an explosive poo. This happened for five nights. Our dietician suggested cutting out soy (which I've probably been eating more of on dairy free diet). I started this from Sunday evening and Monday night was pain and gas free. Can soy leave breast milk this quickly, or is it just a coincidence?

Thanks, all this allergy stuff is new to me and it's overwhelming!

Proteins leave the breastmilk in the order for hours 8-24 usually
When first removing an allergen it can take time for the gut to heal but if you have already started that process by removing other allergens or if that allergen has been in your diet only for a short period for time it will be quicker to see the effects.
My daughter reacted to a lot of foods I ate and I did see improvements with removing some foods 1-5 days after removing the food or after a slip up depending on the extent it was in my diet and the severity of the reaction

Oat would be the next milk to try and there are lots of oat and coconut yogurts available. I particularly liked the coconut collaboration yoghurts and the Jörd oat yoghurts.

Thanks!

I've been on oat milk but there has been soy in other things I've eaten (bread, biscuits). Good to know that it's possible that it's cleared my milk in this time, really hoping that the improvement last night wasn't just a fluke!

With relatively low levels you will often see a quicker recovery than taking out something that is in your diet in large and quite pure forms.

Fingers crossed it continues!
