You can give your baby a formula of goat milk powder that is easy to digest and absorb. It is normal to drink milk naturally after digestion and absorption.
When the baby doesn't want to eat breast milk or bottle, you can try to feed the baby with a spoon to see if it can be eaten. If you still don't want to eat milk, don't force your baby to avoid choking milk and causing aspiration pneumonia. Note that if the baby has other discomfort symptoms, he needs to go to the hospital for further examination immediately to see if there are any other problems.
