Some ideas
Just a couple ideas. 1. Bungee cords and car seats are your friends. be creative down below, babies sleep alot and the motion of the boat is usually a calming event.helps you get some peace during your sail. When they get older, snacks are your best friend, life jackets any time they are up on deck, and let them start slowly neg. the companionway as soon as they show interest. You'll have to help them at first( which is trying at times because they want to go up and down a thousand times!) but they master it sooner and its builds their confidence about moving around on the boat, and pray you get a reader. I did with my first, juries still out on the second. Pray for Wind, Lugeman
