Thick hard poop

What should I do? Pedi said to add apple/prune juice .5oz daily. That helped for a couple weeks then it slowly started to not work again and now her poop is back to thick and hard and she’s crying when pooping.

Any suggestions? Add water?

I’m going to do kora syrup and warm water this morning to help relieve today but it can’t be done every day. And she obviously needs something daily to help her.

Thanks ladies!
