Danni - Congrats!!! it's a great feeling isn't it. Charlie did it once, but think that was the panadol after his shots.
Though I can't get him to sleep during the day, I must admitt he's pretty good at night. He usually sleeps a 6-7hr stretch first up, has been doing that for a couple weeks now.
I hope Mason keeps this up for you. You must feel nice and refreshed today.
