“On my snap chat,” the proud mama, 35, captioned the cute image of her baby boy dressed in all white as he munches on his fingers.
She also uploaded a photo form her app.
“Mermaid party pics on my app and KimKardashianWest.com,” the business mogul wrote about the fun photo of the two girls in mermaid outfits.
“You’re the sun in my morning babe,” she captioned the photo of Saint.
Kardashian recently talked about having her hands full with “energetic and wild” North and “sweet and calm” Saint.
“They look so much alike, but they have totally different personalities,” she said . “All North wants to do is put on a costume and sing and dance. She steals all my jewelry, she loves clothes and she’s obsessed with makeup. Saint sits and smiles all day long!”
