No I wouldn't and never did. Another money making middle class angst thread here. I've got 3 kids, all good swimmers and they started lessons at 4yrs, now aged 8, 10 and 12. My 10 yr old daughter is in a top swimming club and loves it, the other 2 kids love swimming and are extremely good but don't want to compete. Ask yourself who are you doing it for? Just take them to the pool yourself or with a baby chum, they'll not notice the difference. Save your money, they cost loads more in the years to come.
I noticed 'footie' lessons advertised locally recently, from aged 6months! I'll leave you to draw your own conclusions!!
