I say this with love, but I hate all of you with good sleepers

None of mine have been great. And William is one that I don't rock to sleep, put him down awake and he goes to sleep on his own. I cannot for the life of me figure out what I have done wrong to get horrible sleepers :/ I'm so tired of being up so much! At least I can put him down in his own crib easily when he wakes up and I don't have to fight him to go back to sleep. I think that they must have fast metabolisms like me, and they just need to eat more because it's processed faster.
