Prince Harry and Meghan Markle had a family day at The Happiest Place on Earth … taking their 2 kids to Disneyland with the Duchess’ mom Doria Ragland in tow!

Check out the sweet family photos the actress-turned-royal posted on IG Monday — Harry and Meghan hold hands with 7-year-old Prince Archie and 4-year-old Princess Lilibet as they explore the park in … another pic shows Lilibet hugging Cinderella.

And Meghan was clearly happy to have her mom join along, sharing a snap of her embracing her mom, giving her a smooch on the head.

As you know, Meghan and Harry generally keep their kids out of the public eye … but did share a glimpse of their lives while celebrating Archie’s 7th birthday just a week ago by posting a snap of him as a baby cuddled up on Harry plus a picture of Lilibet and Archie walking in the wilderness together.
