I'm aware my current problems may soon be solved by the nights drawing in but.... Dd is almost three and is up and raring to go anytime between 5-6. Im utterly exhausted. She's not one for snuggling in bed and wants to be playing from the moment her eyes open. Are they worth the investment or are they just a bit gimmicky? Is she too young for it? Any other tips on prolonging her sleep greatly received.
