Allergic to milk and almond milk

A❤️C

When I switched to whole milk for my one year old he had diarrhea for two weeks. Switched to lactose free milk, same thing. So in the last two weeks I switched to almond milk! No diarrhea but now he has bumps all over his face like baby acne and it started around the same time after almond milk. My nephew was also allergic to milk and almonds and many other nuts around his age so might be genetic 🙄 same thing happened to him.

So the doctor is recommending soy milk over the weekend to see if the rash goes away. I am gonna do that over the weekend. But, I really don't want to put him on soy milk long term. If you look up side effects online it says it has estrogen and causes increased risk of cancer later in life 🙄. So maybe I'm being paranoid.

Did anyone use the toddler formula for their child? He has fine on Similac sensitive. Been going through this since he switched. Or any other recommendations?

Thank you 🥰
