spitting up..

my sons 7 months and afther eating he spits up....not tons but a little but its not normal for him to spit up... it mostly happens afther hes had baby food or a cookie....not formula.
what could it be...
the heat?
teathing?

Maybe his stomach isn't ready for solids? I would lay off for a while & hopefully that will help...

he started solids at 6 months.....he was fine for about a month...this just started a week ago

Ask your doctor, it could be anything.
