I have a Dd who is just turned 4. She is absolutely fine at the bedtime routine - makes little or no fuss when it is time to get ready for bed (about 6.45-7pm) bath or wash, teeth, toilet, pj's, into bed and a story. This routine haant changws much in the last 3 years! Then we turn the lights off and up she gets, toys out, won't stay in bed, chaos and noise and NO SLEEP! It is routinely 10 pm before she starts to quiet down. Her bedroom is dark (as it has always been) and I appreciate that it is very warm at the moment but this has been an issue since before the nice weather. She has to be up at 7 for nursery so I can get to work and she's so tired in the mornings. What can I do?!
