Feeding my baby is a nightmare

Ok so my 10 month old LOVES to blow raspberries. She does it while playing, diaper changes, you name it. She thinks it’s the greatest thing ever because she’ll do it and then laugh about it. It’s actually super cute, except she does it at meal time with a mouth full of food or formula. By the end of the solid meal I’m covered in it and when she’s drinking her bottle she tries to do it and ends up gagging on it. Yesterday so hard it came out of her nose. I try to correct her, but obviously she doesn’t truly know what “no” is just yet. Is this constant raspberry situation normal that she will grow out of or is this something I accidentally taught her while playing with her? With it interfering with feedings I’m not sure how much nutrition she’s actually getting.
