Kate Middleton is reportedly feeling the pain of her youngest child, Prince Louis, 4, getting older.

Kate Middleton shared a sweet photo of herself and her kids for U.K. Mother’s Day.

The second picture shows Kate cradling Prince Louis like a baby.

Body language expert Judi James says this pose captures her emotional side.

The pose suggests there are bittersweet emotions about losing constant mother/baby contact.

Middleton visited Royal Surrey County Hospital and remarked on Louis growing up.

She shared nearly the same sentiment in July 2022 after spotting a newborn.

Middleton is looking at old photos and videos of her kids after they go to bed.

She can keep on cradling Prince Louis as he'll always be her baby.
