Kate Hudson and ex-hubby Chris Robinson's son Ryder is just preppin' for the big leagues!

The adorable 7-year-old arrived to his little league game in Malibu escorted by a nanny, as his many months preg momma was probably resting at home.

The little Yankee is gearing up to welcome his first new sibling, and he's getting a new stepdad (Muse front man Matt Bellamy) too! Hudson and Bellamy became engaged shortly after the pregnancy was announced, so it's an exciting time for the whole family.

We bet little Ryder will make a fantastic big brother!
