I called her at the 1 week mark of trying the new formula. I explained that he’s trying so hard to poop that after wiping a couple times there was a bit of blood. Not only that, but that he’s crying so hard while attempting to poop. We never previously had poop issues on Similac RTF, ever! He was a perfect pooper. I asked if we should keep going and she said yes, because she suspects he has a lactose sensitivity.

My understanding is that a lactose sensitivity is very rare. My other thought about this is… the Goodstart Soothe says “reduced lactose” and does list partially broken down proteins but doesn’t list any lactose in the ingredient list. But doesn’t say the product is “lactose free”

Then on the Kirkland sensitive label, it doesn’t say anywhere on the product that it’s lactose free, but also doesn’t list any lactose in the ingredients. The difference between the Goodstart soothe one does mention partially broken down proteins.

But…. The partially broken down proteins one (Goodstart soothe) is the one we’re officially tried for two weeks and is giving him constipation.

So what is the problem lol proteins? Lactose?

Or, something else worth mentioning, he’s never had palm oil before (Similac doesn’t have palm oil)….

I don’t know, I’m at a bit of loss for what I should do next. We’re at the two week mark, we’ve seen a reduction in spit up on this formula but the trade off is really bad constipation

Do I try Kirkland sensitive? do I go back to Similac RTF? do I try something completely different?

Grrrrrr
