Kim Kardashian debuts photo of baby Saint

Kim Kardashian has shared the first photo of her three-month-old son Saint West.

The reality television star gave birth to her second child with her rapper husband Kanye West, a boy named Saint, on 5 December last year (15).

In the cute snap posted on her website on Monday (22Feb16), Saint is shown dressed in a white onesie looking very relaxed with eyes closed and his arms up in the air.

In an accompanying caption, Kim explained that she decided to post the image in honour of her late father Robert Kardashian's birthday.

"Today is my dad's birthday. I know there's nothing more in the world he would have wanted than to meet his grandchildren. So I wanted to share this pic of Saint with you all," the proud mother explained.

The 35-year-old had previously shared a photo of the little one's fingers clasped around his big sister North's hand. In the caption for that shot, Kim revealed two-year-old North had been calling her baby brother her "best friend".

While Kim and Kanye, 38, had held off on sharing photos of their newborn immediately after his birth, there was plenty of discussion surrounding who the baby boy most resembled.

Longtime Kardashian family friend Malika Haqq previously said that Saint looked like his big sister, who is affectionately nicknamed Nori.

Meanwhile, Kim herself had joked that Saint shared features with her.

"He's so cute, you guys, you have no idea," she said of Saint during a live stream with her brother Rob Kardashian. "He looks kinda like just like me, don't you think? He's so cute - he looks just like me!"
