Toddler and PFD''''s or Harness
We liveaboard and sail with our 2 yr. old and 4 yr. old. They always wear their life jackets whenever on the docks or on deck. We also have the lifeline netting and I agree with Russ, it''s the best thing we did. Once the life jackets get a little worn in, they are pretty comfortable. We have the yellow mustang jackets that Russ was talking about. They are great! My son forgets he has it on sometimes when he comes down below. We don''t have tethers for the kids yet, but we don''t plan on doing any extreme sailing and if the weather gets bad, we will just go down below. We will probably re-think everything when we go off shore, but what we have now works great here in the Pacific Northwest.
Best of luck
