At what age roughly is the right age for your little one to sleep in a bed. I mean my son is 19 months and has a cot bed. He has the sides up at the moment but i was just wondering when the right time is to take the sides off. He is great at night he sleeps right through i never hear a sound from him during the nite. I just worry that if I let him have a bed that he will get up all the time and play with his toys.
