The kids giving each other a hug after their swim to provide warmth for each other.
When I was young, I always envy friends who have closely knitted extended families where the cousins are of similar age and they play together. For me, I have a huge age-gap from my cousins (I have cousins as old as my Mum, that explains how huge our gap are) and we are not close. So I hardly sees them, let alone play with them.
I’m glad my kids are in a better situation. Their cousins are just 1 and 2 years older and they play together a lot. Besides, Chubby is quite closely knitted with his extended family on his mother side. So the kids have other uncles to play with.
