I did it! Tonight! 10 lengths!
Back story, I had appalling SPD with ds2 and it took 9 months of physio for me to be able to manage to walk more than a couple of hundred metres in one go and tonight I finally managed a proper good swim, mainly breast stroke too! I'm feeling chuffed to bits with myself! Ds2 is 14 months by the way and I feel great! I've been working out doing yoga, etc but not been brave enough to take the plunge (pun intended)! Hooray me!
