GERD?

My month old has been showing symptoms of GERD. She fusses after eating, spits a lot of it up, we keep her upright for a while and try feeding her again but she spits that up too. And she's basically screaming the entire time she's waiting. Tonight I'm noticing she's kind of wheezing in her sleep. I know I'm playing doctor, I just researched her symptoms and GERD checks all the boxes. Of course I won't be sure until I talk her to her pediatrician.

But if your baby had GERD, what was the treatment like for you? Did the basics help or did your lo have to have surgery? Just want to prepare myself I guess.
