Toddler climbing out the cot WHAT DO I DO NOW ???

Emma

So my 2.5 toddler was climbing out her cot last night for the first time what did all you ladies do when your toddler did this ? Even know she is almost 3 she is a little bit behind her age I feel an her nursery feels the same so I'm a little scared about her going into a toddler bed any advice would be great 👍🏻
