I have 2 daughters that love their sleep.

DD1 in bed at 8:30 and wakes up between 8am & 9:30am. She also still has a 1.5 - 2hour nap in the afternoon. Amelia is 21months
DD2 last feed around 9pm in bed by 10pm and wakes around 7:30am. Macey is 9 weeks old now.

They both take after their mummy I guess. I love my sleep too.
