Just to add: My son (3) didn't sleep through the night the entire first year of his life. Not one single night. I was a walking zombie. However we don't know if ds is GT like his big sis.

Also my dd never slept the amount of hours suggested for her age. Early on when they are said to get about 14hrs of sleep, dd would only get 10. Now that she's older Im not sure what is common but she sleeps about 9 hours.
