Spit up

Any other moms have a very spitty baby? My pediatrician said it’s more a laundry problem then an actual problem. She never cries, doesn’t spit up violently, and it’s not a TON, it does seem mucousy, and it’s literally every time she feeds there’s something coming out 😣. She is gaining weight and happy, so they’re saying she’s just a happy spitter...any suggestions to help with this though?
