Should I give cow's milk to my 3 month old?

Nope, wait till he reach 1 y/o. Because cow milk is hard for his immature kidney to process, and also contains less iron than breast milk or formula milk. If you can keep on breastfeeding, pls do so. Even if you cannot direct latch, you can pump it and use bottle. But if your yield is really really low, or some other problems, you can ask someone else to nurse your baby or donate her milk to your baby to consume. This ensure your baby still gets the best milk,which is breast milk. if you insist of changing, formula milk is better than cow milk. At age of 3 months, your baby kidney is not well develop to process cow milk and may lead to other health conditions such as anemia.
