6 years ago as a surprise for my then 4yr old daughter we bought a pretty pink mosquitoe type net to go over her bed, not sure what you call them! What we did was before Christmas Day my DH put a hook in the ceiling aove the bed ready, she didn`t notice it amongst all her paper chains! Then on Christmas Eve when she was fast asleep we put it up, draped it round her bed, not fully, and I added some sparkly butterfly stickers as she loves butterflies!. It was just magic to hear her in the morning when she woke up, she still has it up there now.
