dd 1 is about to start school in september. she goes to bed at 7.00-7.30, and needs 12 hrs sleep. the trouble is, her 2 yr old sister wakes her up a 6- 6.30 and she is then exhausted by early afternoon. as a result she often has a good 45 min nap in the car to catch up on sleep. i'm desperate to sort this out before she starts in reception, as i don't know how she'll cope. any ideas/ experiences with tired school starters?
ps the girls have seperate rooms, but my youngest is impossible to keep quiet when she wakes.
