Glad to hear you got him onto the inner health plus (probiotics), as this will replenish his stores of beneficial bacteria - the deficiency of which causes thrush to develop in the first place.
Thrush usually occurs in little ones if they have been exposed to antibiotics, either directly or indirectly via breastmilk - as the antibiotics cannot discriminate between good and bad bacteria - they effectively kill both. When good bacteria becomes depleted, the small amount of yeast that lives in our digestive system naturally is able to grow out of correct proportions and thats when thrush develops. Replacing the beneficial bacteria with a probiotic supplement is paramount to preventing thrush (yeast infections) of any kind.

Make sure you keep the probiotics in the fridge!!
