Acid reflux babies

If your baby was diagnosed with acid reflux, were they fussy or anything?

Adalynn spits up quite a bit. She has since birth. It got a little better and recently picked up. I figured it was worse because of teething. She spits up as soon as we put her in her carseat or if we let her play after eating. I have to keep her in her swing, which sits at a slight incline for about 30 mins after eating. She spits up but doesn't really seem to be affected by it. We both go through about 2-3 outfits a day. Her appt is on the 19th and was going to ask about it. I just want to make sure she's getting all the nutrients she needs.
