<human>: Can you succinctly summarize the text in 1-3 sentences?

Last night I had to bring a rather large box down the stairs and my 3 year old was already halfway down. I began my descent, slowly one step at a time.

Unfortunately 3 year olds tend to be quite short so I didn't realise she had stopped.....until I knee'd that poor kid in the back and sent her flying. Luckily our stairs curve round so she didn't have far to fly and she bounced off the wall quite safely. A little lip cut nothing horrific.

Bedtime comes so it's time to say goodnight to her Dad (he works very late and did not witness the 'incident') on FaceTime. Thinking I'd got away with it I left them to chat before I hear 'OH, and mummy kicked me down the stairs'. She offered him no explanation just told him that and said goodnight. Her Dad is now probably weighing up the costs of some hidden cameras to check what the hell I do to this child while he's at work.
<bot>: heavy box blocked my stairs view, I kicked my child down stairs, she grassed me up instantly to her dad at work.
