Almost 7 month old spitting up a lot

Am

For the past week, my daughter has been spitting up a lot after nursing. Sometimes it’s right away, other times it’s not until 10-15 minutes later.

She use to spit up just a little bit occasionally but this is a lot all at once 2-3 times a day (sometimes slightly projectile). My diet hasn’t changed at all but we introduced solids about 3 weeks ago.

Could this somehow be related to starting foods or does anyone have an idea what would cause this at her age?
