Thanks for your query.
It is normal for breast fed baby to pass 5 to 7 motions a day and is due to gastrocolic reflex.
Monitor her activity,urine output,feeding pattern.,any fever
,any blood or mucus in stools.
If everything is normal you need not to worry.
You should avoid gas forming food items in your diet and decrease dairy products for few days.
Wishing your baby good health.
