Your son is 10 months old and has very loose stools you do not know if this is normal or not but what can you do to help this?

Juice was often the cause of loose stools in my children at that age. They really don't need juice at all, especially if they are eating fruits & veggies. If the baby is thirsty between formula/breast feeding, try some water (although mine didn't like that too much) or water down the juice.

Antibiotics also can cause loose stools.

Hope this helps.
