Both my boys started lessons at 3 months and I'm really glad we started early as they have loved it from day one. Jack is now very competent in the water at just 2. I think it's harder for them when they start older.

I second what Trish said about the one on one lessons. I'd try this first before giving up. If she is still distressed then I think maybe stop for a term or two but make sure you take her swimming lots of times and get her used to it. Then try the lessons again. I totally agree with Trish that water saftety is just too important.
