Spit up 😩

My son (10 weeks) spits up SO much. Like 3-4 times after he eats then sometimes when he wakes up from a nap. I have cut out dairy, soy, and wheat and it really hasn’t made a difference. I hold him up, nurse him at an incline and reclined to help with my letdown. He’s a Happy spitter. It’s just sad to see him (...and me) covered in spit up all the time... and it’s a lot of laundry. Any other suggestions???
