It's only the second time the Keeping Up With the Kardashians' star has shared a family portrait - and she has said it's not easy getting them all to pose, the Daily Mail reported.
She captioned a previous Instagram post: "I don't think you really understand how hard it is to take a good family pic. This was all we got before all three kids started crying. I think I cried too."
And sharing the same photo on Twitter at Easter, the 37-year-old beauty admitted everything wasn't as serene as it seemed in the shot.
She wrote: "One hand holding the baby and the other hand grabbing the back of Saints shirt because he kept running away lol.(sic)"
Kim recently admitted she was 'shocked' that her oldest daughter North has been so 'nice' to her baby sister because she struggled to adjust when Saint was born.
She said: "They love her. I'm so shocked that North is so nice and she's still... it's her world and she's the sweetest, but it's more like she and Saint have a thing. She's very warm with her sister."
And Kim thought Saint would've been riddled with jealousy when little Chicago entered the household, but he smothers her in 'kisses and hugs' every day.
She explained: "I was more worried about him, that he would be more jealous, [like] how North was with Saint. But he's so good with her. Every day he has to give kisses and hugs. Literally, as I was walking in, [I was looking] on my phone at the video Kanye sent me with the kids trying to climb into her crib."
