'So adorable' - Ivanka Trump melts hearts in make up-free cuddly snap with son Theodore

Her Instagram feed is usually littered with glamorous shots with members of congress in designer clothing, but Ivanka Trump proved even she likes to relax in comfy garms and hang out with her kids.

The mother of three, 36, has been ultra-busy with her role as advisor to her father President Donald Trump over the past year, which is evident from her Instagram page.

But the former US television personality – who is married to Jared Kushner – let her hair down for the latest social media snap, which showcased her maternal side.

Trump lovingly embraced her son Theodore, one, with a big brown teddy bear that was longer in length than him, and went make-up free for what looked like a bedtime photo.

Sporting undone hair with white pyjamas in her children's nursery, she captioned the heart-warming shot: "The perfect way to end the day! " in a post to her 4 million followers.

The picture proved to be the most popular of her Instagram posts in while, garnering over 204K likes in just 13 hours.

One fan wrote in the comments section: "Awww so adorable❤️❤️❤️" as another said: "you both look like angels."

A third added: "How Cute Mommy and babyHow sweet".

Others touched on how Trump works too hard to spend quality time with her children, with someone else stating: "Sorry, but his perfect day would have been to have had his mommy be the one who had taken care of him all day."

Trump has been thriving in her new political role after moving to Washington DC at the beginning of the year, when her husband was appointed senior adviser to her president father.

She began serving in her father's presidential administration in March 2017 – assuming the official, unpaid position after ethics concerns were raised about her access to material while not being held to the same restrictions as a federal employee. Trump is now considered as part of the president's inner circle, later becoming an official employee in his administration.
