Vomiting Yellow Mucus
by Andrea Jackson
What could be the possible cause for my 6 months old baby to be vomiting more than once within a few hours, clear to yellow mucus?
I am worried that she is sick.

Why A Baby May Vomit Yellow Mucus
In my experience, the most common reason why a baby vomits mucus is because of a cold
When the baby has a stopped up nose and a lot of mucus from a cold, they tend to swallow it. And then, especially if the mucus is thick, many babies throw it up. It can happen while coughing and other times too. Babies tend to throw up more easily than adults.
Some babies also vomit more easily than others. Does your baby spit up a lot? If she does, then it probably doesn't take too much mucus for her to start throwing it up.
Another possibility would be that your baby has a stomach bug. In such case, after emptying her stomach content, she could be vomiting mucus. But you don't mention any particular signs of illness, so my bet is a cold.
Finally, she could be teething and thereby swallowing more salivia than usual - and then spit up clear to yellow mucus/salivia.
Does any if this make sense for your baby?
