I have a 7yo DD, and three weeks ago I fell down the stairs. Both flights, with some weird pivot move on the landing. Nothing broken, but a shock and quite painful.
I tried to play it down so as not to worry her (I’m very aware of avoiding the kind of parentification I got dealt as a kid).
DD came immediately. She was worried, solicitous and empathetic. She stroked my head, helped me up and offered to get the frozen peas for my bruises. She was a darn sight more assistance than my DH, who I think gets useless and paralysed in these situations.
I know different kids have different personalities, but I think you are right to be a bit concerned. Your 7yo is not too young to show active empathy as some posters are suggesting.
I’d be googling ‘encouraging empathy’ strategies for primary school aged kids.
And
for your fall, it’s a horrible feeling. Kinda clumsy, scared, shocked and sore all at once!
