Trainig with Wood Playing with Metal

I didn't even touch my aluminum bat until the moment of BP at a school's recruiting camp and I did just fine. It's really not that hard of a transition back to aluminum, he should be fine if he uses the mechanics he learned with wood.

hmills- You have probably heard a lot about the difference in a person's swing with metal vs. aluminum...That is false. There are no differences in your swing with the different bats. The difference you hear about refers to the difference in results; a home run hitter with a metal bat won't necessarily be a home run hitter with an aluminum bat. Therefore, that hitter who might be trying to hit home runs with metal cannot do so with aluminum because it would result in just a long fly ball out. The difference in the swings is the adjustment that has to be made because of the different effects of each bat.

In terms of your son, he will be fine. I haven't swung a metal bat since my high school season ended in late May and I will be completely fine transitioning back from the wood that I played with in the summer and fall and am training with now. With solid mechanics and a good fundamental mental approach to the plate, it is irrelevant what kind of bat is in your hands. Just see it, and hit it.
