I put my bub into a big bed at 15 months, she is a climber and at 23 months she climbs and swings of everything and anything she can find. I found putting her into a bed with a rail at 15 months it was the easiest thing, it wasn't even an issue, it was a lot harder with my first 2 kids. I took the rail off at about 19mths, because she thought it was fun to jump over the side of it, it was further to fell over the rail then off hte bed :shock: She did hit her head!

She has only fallen off the bed a couple off times lol
