Fortunately little Astala escaped unscathed from the incident, but as the photos show, it could have been so much worse.
Concerned Peaches was snapped immediately scooping up and comforting her four-month-old son as the contents of his buggy lay strewn on the pavement.
Peaches later took to Twitter to vent about the state of London's roads and how something should be done about them, writing:
'It's impossible to see these cracks when pushing a pram. The Mayor of London should do something about it. It's ridiculous!'
She went on to explain via Twitter that Astala was 'strapped in, the weight of his body popped the buckle open as he fell. And he was totally fine, wasn't hurt AT ALL'.
The young mum is often spotted out and about in London with Astala in his pram. Let's hope this scary incident - and the ensuing media interest - doesn't put her off her daily walks.
We're still not quite sure why she couldn't get rid of the phone while tending to Astala. But hey it was probably an important call.
Have you ever had anything like this happen? Tripped up the kerb with your buggy? Got the wheel stuck in a hole?
