A son. Congratulations. Being a parent is AWESOME.
I was worried that my son might have inherited my gender dysphoria. He is 5 now (about the time I started liking "girl stuff"), and I have been watching for any signs, and nothing is apparent. He seems about as comfortable in his gender as any 5 year old boy can be expected to be. This makes me happy, because I know that my dysphoria was a struggle for a long time, and it is a struggle I hope he does not have to go through.
