Anyone else?

My LO has been way more gassy lately and spitting up more. She wakes up in pain from it. At first I thought she was spitting up and waking up because of teething, but there's no tooth in sight. Then I noticed the gas. I've been giving her gas relief, but I'm starting to wonder if it's because of the solid foods I've been trying to give her. We've been exclusively giving her Gerber stage 2 (and formula, obviously). But I've been trying to feed her from our plate (mashed potatoes, sweet potatoes, some noodles) and now she's gassy. Is this normal? Or should I call the doctor? If you have any other ideas, please let me know! Thank you in advance!
