Title says it all...
DS, 6 has not been swimming until recently due to health issues. He has had half a term of weekly lessons and a week of daily half hour lessons where he has progressed massively. We are going on holiday where we will have access to a quiet pool and would like for him to keep doing the kind of things he was doing this week. (maybe I should have been taking notes but was too busy cheering him on as he went from sinking to swimming a width on his back without floatation!!)
