What do you do for entertainment on board a ship with a toddler and a baby? Swim! We swam in the morning, followed by nap, then afternoon swim, followed by nap, then night swim. Swim swim swim.. Sure was fun coz the pool water was nice and warm. Ben just kept splashing and kicking until one point he was so tired from all the swim that he just chilled out in the float, and just floated through the night..
