Coolest first moments

[GertaS]

Hey everyone

I was just reflecting on my 10-year-old daughter and 6 months old son growth and special moments. It gave me an idea to start a thread what have been to you to most precious and coolest things you kids did for the first time?
For me some that come up is the first steps, words, older daughter playing Frozen music on the piano which daddy taught her, the first time by the ocean, first snow for my little one etc. There are so many. Which do you cherish the most?

Lots of dc here. Always the first slobbering kisses and attempts at saying they love you...
One of mine had club feet and 4 years of gruelling treatment - for him the time he wore his first football boots - I sobbed..
Too many to tell...

DS 22months meeting baby DD for the first time, and giving her a kiss for the first time. That had me welling up.

4th DC was born with a port stain on her arm. It was the first thing I noticed and I fell in love with it.
