Sink or Swim

We spend the entire summer at the swimming pool and the whole family loves it. Karson is a good swimmer but just refused to enter the big pool this year. Last year he went all over the pool doing the slide and diving board. I think a lot had to do with mom not swimming much this summer since she was pregnant and not able to swim after having Kelton. Korbin is the exact opposite and loves to swim. He will go with anyone off the slide or board. Goes underwater and comes up smiling.
Trouble, Korbin???

Higher the better!
