This ship is great.  The size was great for keeping inside for the first few weeks after Christmas and now it is outside on warmer days.  We have had three toddlers playing on it with no trouble.  My son and 5 yr old daughter can play on it together as well.  The 15 month old can't climb to the top yet but that is good.  We put him up there sometimes but stand next to the ship because it would be better if the side railing were a bit higher.  I feel it would be really easy for him to just lean over and fall off.  Overall I am really pleased and would say in another two months it won't be a concern anymore.
