If your child has been up all hours over the Christmas and having nice lie-ins in the morning, to get him back on track for school next week you should start adjusting his sleep schedule now. This will ensure he does not start off the new term on the wrong footing.
You can start to adjust his sleep schedule by awakening your child a half an hour earlier in the morning for 2 mornings and putting him to bed a half an hour earlier each night gradually over the course of the week. Wake your child earlier and put your child to bed earlier until you are back at his regular bed time.
It is important you don’t just tackle this on Sunday night. When people do this normally what happens is the child won’t settle until late on Sunday, this may lead to overtiredness on Monday night and again the child will find it very hard to go to sleep. This can then have a knock on effect for your child for the rest of the week. Sometimes this can lead to longer term sleep issues as the child loses the ability to settle themselves to sleep as their body clock is all out of sync.
