I have 3dc - 6yo dd and 2.5yo dtds. Dtds have just dropped daytime nap so bedtime has moved to in bed and settled by about 7pm rather than 7.30pm. Dd1 goes to bed by 7.45pm.
I googled bedtime and came across an old netmums thread where they all seemed to put toddlers to bed at 8-9pm. I decided to come back here to ask what's normal in your house? Maybe I just have tired children. They get up about 7am which is enough time to have breakfast and get ready for the school run.
