Gentlease Question

Kelli • 31- Married 💗 - Momma to a sweet girl 💕 Expecting Baby #2 in January 💜

My LO's pediatrician recommended on Monday that we switch to the Gentlease Enfamil formula from the regular Enfamil for a week or so while she gets through this pooping change that happens around one month as she was a little constipated. Now it seems like she's really struggling to poop, and what comes out is super thick and pasty. Is this normal? Has anyone else ever dealt with this?
