Hope your dd is ok,is she worried?swimming is great I love it. I am 37 and go nearl every day, I am a strong swimmer but not good, recently I went for lessons, just to get my strokes to look better if you know what I mean. I could not do the crawl.(can now) My instructor was amazing, I had a block of 8 lessons, often the others would not turn up, I had to pay them up from unlike the others( didnt work so didnt pay)so I went every wk,,so that was great, got the instructor to myself, my point is your son is lucky that you encourage so much, wish I had got that chance.
