What a cutie! It’s been two months since Pippa Middleton and her husband, James Matthews, welcomed baby No. 1, and on Dec. 29, Kate Middleton’s sister stepped out with her baby son, Arthur, during a St Barts trip to the Matthews family hotel, Eden Rock.

In the series of pics, her little boy looked adorable as ever craddled in his mother’s arms. The snapshots even featured proud daddy James and his brother, Spencer Matthews, who also recently welcomed his own baby boy.

In October, Daily Mail‘s royals correspondent, Rebecca English, was allegedly the first to report the news of baby Arthur’s arrival by tweeting, “[Prince] George, [Princess] Charlotte, and [Prince] Louis have a new cousin! James and Pippa Matthews (Middleton) have had a baby boy. He was born Monday, Oct. 15 at 1:58 p.m., weighing 8 lbs and 9 oz. Everyone is delighted and  mother and baby are doing well.”

The 2-month-old’s sweet middle moniker, Michael, pays tribute to Pippa’s father, Michael Middleton, and James’ late brother, Middleton, who sadly died at age 22 in the late ’90s. So sweet.

Here’s hoping we get to see more of the bundle of joy in 2019!
