How to solve the problem of the baby not being able to eat formula milk

Patient's question:

Patient Age: Two months
Detailed Condition and Purpose of Consultation: My baby is two months old, and the milk supply is not enough. I have bought three types of formula milk, but none of them can be tolerated. She vomits immediately after drinking, and the vomiting is quite severe. After vomiting the formula milk, she also vomits all the next feeding of breast milk, and it comes out in a (projectile manner). I have also tried gently patting the baby, but it hasn't helped. What should I do?

Doctor's answer:

For babies, the best food is breast milk and formula. Never give them random things to eat. If there's no breast milk and the baby won't drink formula, the baby will be very uncomfortable at this stage, and it could get worse. You can cook some thin porridge in a clay pot, making it very soft. Add a drop or two of camellia oil and a tiny bit of salt—very, very little. See if the baby will eat it. If not, buy a can of infant cereal and visit a place that sells baby formula, where someone will recommend it to you. Also buy a can of glucose or high-quality honey and mix it with the cereal like you would with formula. Add some glucose, but never put in white sugar. However, the mixture shouldn't be too thin or too thick. If the baby's stomach feels uncomfortable, buy a powder called "Mama's Love" to regulate their digestion. My daughter was the same way, and I did it this way. But she was allergic to formula, so you need to be careful. Check if your baby gets red, bumpy patches on their face after drinking formula. If not, that's good. If they do, pay attention. Babies shouldn't eat random things—be very cautious.
