By social custom and tradition, you should not feel as though any burden has been placed on you. However, because you love and want to support your son and are getting a new daughter (and in-laws, for better or worse), your feeling the need to do something is good - and normal. So, I suggest that you and your wife talk the situation over with your son, discuss their plans and "wants" and their financial preparation, then make a decision about how much you want to add, do it, and get quiet.
