For a 6-month-old infant, it is very important to use probiotics like Procillus (Bacillus clausii) only under the guidance of a pediatrician. Typically, the probiotic is given in a form suitable for infants, such as a suspension or mixed with a small amount of breast milk or formula.

Here are some general points to consider:

• Dosage and administration: Follow the exact dosage recommended by your child's doctor. The doctor will consider the infant's weight and health condition.
• Method: The spores can often be mixed with a small amount of water, breast milk, or formula and given using a dropper or spoon.
• Timing: It is usually given after feeding to help with digestion.
• Safety: Always ensure the product is suitable for infants and check the expiry date.

Since infants have delicate digestive systems, self-medicating with probiotics is not advised. Please consult your pediatrician before starting Procillus or any probiotic to ensure it is safe and appropriate for your baby’s specific needs.
