Because of some of the evidence suggesting milk is unhealthy, I suggest you skip the cow’s milk. However this does not mean that calcium is unimportant. Calcium is vital for bone health. 
Bone health is incredibly complex, involving many other nutrients like protein, phosphorus, vitamin D, and sodium and lifestyle factors like exercise. Government-recommended calcium intakes are controversial and could themselves be the topic of a huge, long discussion, but the bottom line, in my opinion, is that individuals should consume at least 500mg of calcium daily from a whole-foods, plant-based diet.
