As a Catholic, can I baptize my own child after he is born?

As a Catholic, can I baptize my own child after he is born? I am about to see my first child be born and was wondering if it would be sinful if I were to baptize him myself after his birth. I am aware that the sacrament can be validly administered without a priest as long as the sacrament is performed with the proper form. I can't see any reason why it would be a problem but for some reason my gut is telling me no. I'm wondering if there is anything to reference that would point to this being sinful despite being legitimate.
