Thanks for your query.
It is normal for a breast fed baby to pass several motions a day,it is due to increased gastrocolic reflex.
Give exclusive breast milk.
Give lactobaccilus sachet for 2 to 3 days.
Mother should avoid gas forming food items in her diet.
watch her activity,feeding pattern,urine output.
In case symptoms persist get her evaluated by pediatrician
Wishing your baby good health.
