Swimming lessons

I've been very lax. The kids gave up swimming lessons a couple of years or so ago and it wasn't until I got nervous watching my son in the river one day that it occurred to me that although he can swim, he can only swim for as long as he can hold his breath. So here we are to rectify that. He did very well in his first lesson. Within half an hour he went from a few floppy arm strokes to swimming 10m freestyle with breathing! I am a proud mum!
