He was born on Nov. 21, just in time for the holidays — and he's certainly getting into the spirit. For the festive photo, the niece of former President George W. Bush dressed him up in a winter onesie and hat, placed him on a red and green scarf and surrounded him with gifts.

This isn't the first time James has posed for Instagram. Two weeks ago, Lauren, the founder and CEO of FEED Projects, covered the cutie in branded FEED clothing from head to toe.

The family is also looking forward to TODAY special correspondent Jenna Bush Hager's baby girl to arrive in August.
