My dd is almost two and I have put her in a big bed as we need the cot for number two in a month. I don't want to buy another cot. She was a great sleeper in her cot, 2-3 hr day naps and 12-13 he's at night without a peep. I thought she'll be fine going into a bed but she just keeps getting up and playing, won't come out of her room, how do I keep her in her bed? As soon as she hears me coming or as soon as I walk in she runs and jumps into bed so she knows what is being asked of her. I have to lay with her and she'll go to sleep within minutes. Tips anyone??
