Toddler seen photographing mom causes a stir

By the looks of things, the little boy in the video will not be stressing about the career he wants when he is all grown up. He seems to have a knack for photography, along with a great background story.  

The internet is in a tizz after a video and pictures were posted online of a young boy standing on his pram taking photos of his mom posing.

The young boy is seen holding a phone as he balances on his pram. Across the road his mom is seen striking a few poses against a coloured brick wall. Those that take pictures frequently would agree with me in saying that a background makes the picture.

The person filming the boy is heard saying, "That's the saddest thing I've ever seen".

The word 'Heartbreaking' is also used and there's a comment saying, 'this is a little bit sick'.

Am I missing something here though? I don't see why this is sad?

I'd be more worried about the safety of the toddler who is seen balancing on the pram?

Surely him falling and possibly hurting himself is more of a concern?
