toddler wears for flower girl

Cf parents i have a question ? My daughter's been throwing up lately but shes not running fever or fussy i feel like it's just the mucus coming up since she's only 8months and always swallows it & can't spit it out Is this normal ? Did yalls kids throw up when congested at a young age? I don't want to call her specialist bc they'll just say do her treatments more.. toddler wears for flower girl
