In one of her snaps, the actress and her family posed in front of the park's famous Sleeping Beauty Castle.

Alba, Warren, Honor and Hayes were also all smiles as they made the most of their time at Disneyland's Jungle Cruise attraction.

The actress's youngest child threw his arms in the air while enjoying his time on one of the park's rides.

The Fantastic Four star and her husband both held their son as the three posed for a snap outside the park.

Alba also included a shot of herself forming a heart with her hands while playing “It's A Small World.”

The actress and her husband, who met in 2004 and tied the knot in 2008, welcomed Hayes in December 2017.

The happy couple started their family with the birth of Honor in 2008 and welcomed Haven three years later.

Since then, Alba has shared several photos and videos with her youngest child on her Instagram account.

The actress recently spoke to E! News and discussed what she admired most about her son.

She explained: “He's not confident at all and I love that about him.” But then he still has that tender side and likes to cuddle. I love it, I love every second of it.'

Alba then talked about how her children had learned to be open about their worries at home.

“My children definitely teach me.” Each of them has their own little needs or what they need from me or what they want from me. “I love that they’re not afraid to share it with me,” she said.
