S.T.
I agree with the others, her bedtime is too early. At that age my girls went to bed about 7 and by age 2 8 PM with only one nap. I'd put them to bed earlier then 8 but my olders don't sleep much and keep everyone up anyway so 8 works for us. Definitely try moving her bedtime to 7 and see if that helps.
As for leaking, I never breastfed my son because he was stillborn but that was 6 months ago and I still have milk. It's not leaking, though. Just give it a little time. Every body is different.
