When he is also the father of your grandchild
The birthday after his first child is born changes what the gift can mean. He is now doing something in your presence that you have opinions about — fathering — and the safest gift is the one that acknowledges that without evaluating it.

Years in, he is one of yours
Somewhere between the fifth and the tenth year the son-in-law tension dissolves and you can buy the same size gift you would buy a son. The trick is doing so without turning it into a speech.
