Thanks for your question.
All babies spit up or vomit, and it sometimes comes up into the nose since the nose and throat are
connected. Pediatricians divide spitting up into either a "nuisance" or a "problem". It is a problem
when the baby does not gain weight due to the spitting/vomiting. It is a nuisance when it gets over
everything and smells bad but the child is healthy and gaining weight.
To decrease the likelihood of the spitting, make sure your baby has burped after a feeding before
you put her down in her crib. It may also help to hold her upright for a longer time after feeding
before you put her down. If you are using formula, a bottle system with a collapsible bag like the
Playtex Nurser often will decrease the amount of air swallowed.
You should check with your pediatrician about the vomiting. Often, just a quick visit to the office
for a "weight check" will reassure everyone that the baby is okay, and that the spitting is a
temporary nuisance but not a problem.
