Hi
When we switched our 2 1/2 year old to her toddler bed we started a sticker chart. I put in on the wall where she could see it from her bed and bought stickers of characters she likes. I made a column for naptime and bedtime and she would get to put the sticker on after she slept and didn't get out. When she filled up the chart after 1 week she got to pick a prize. Either a small toy or an activity outside the house. It worked great- it has been 5months and she still calls for me in the morning and doesn't get out by herself which is great for safety, etc. Good luck!
