What is the cutest thing your kid had done for you?

My daughter wrote her first poem that was in praise of my wife and me and that she did when she was only 6 years old. That was the most beautiful thing she'd done for me. 

For me everything that my son does is a cute gesture for me. But the best times are when he shows his concern and care when I'm unwell

Being a small baby, the fact that she stays up and waits from me in the night, is the cutest thing she can do for me.
