Deb, Maddy is almost 7 & yet on W/ends will go to her room & play, but actually pops herself to bed & can sleep for 3-4 hours!

I recall waking her once or twice for dinner as a 8 month old & having her scream down the house for 30mins as she was simply not ready to wake, after that I just let her sleep!
But maddy could nap from 2-6pm, eat dinner, have a bath & go straight back to bed!!!
