baby puking

hey mamas, my baby is 3 weeks 3 days and is exclusively breastfeeding, well about 20 mins ago he ate for 15 ish mins and then puked so we went and i gave him a little bath since it’s been a week anyway, well after the bath he puked again and now 2 more times, i burped him and now he’s eating again but what would this be from? i haven’t rated anything different today but i had taco bell last night but he didn’t puke throughout the night during any feeding or after.... is this normal ??
