We moved DD into her bed a few months back, she'll be two at the end of this month. She started with one of those flat toddler pillows, but she now falls asleep with a normal pillow, but always ends up in with us anyway. The change was incredible. She went from being tense and unhappy, even in sleep, when we tried to put her to bed, to her willingly going into her own bed. climbing in, pulling the blankets up and waiting for her story. Best thing we did at the time. I was also concerned, she was so little, everything I had read said wait until two, but as I've learned on here - trust your instincts! And she has never fallen out either. I had her fold out couch beside it for a few weeks, but she never fell out.
