Meanwhile, a young boy is playing with some colourful blocks and a ball on the floor nearby.
Both women look similar, with pale skin tones and brunette hair.

However, there are some subtle differences - can you spot them?
The one on the left has slightly darker locks, cut into a short bob, while the other has longer Auburn-coloured strands that fall just below her shoulders.
One is also wearing a green dress and flat shoes, while the woman on the right sports heels, a skirt, and a stripy top.
However, there are a couple of details that make it obvious who the mum is.
Be quick if you’re still working on it, as we’re about to reveal the answer!
You guessed right if you thought the woman on the left-hand side is the boy’s mum - and there are a few little giveaways that you might have picked up on.
First, both the mum and son have the same dark brown hair.
You might have also picked up on the fact that he was facing her while playing with his toys, suggesting he feels comfortable under her gaze.
Also, the woman is leaning slightly forward, which some suggest reflects her desire to watch over and protect her child.
The other woman, wearing the red t-shirt, appears to be more relaxed and has her back placed against her chair.
