Sleeping was our biggest challenge with our firstborn. We co-slept and nursed to sleep. We held hands and sang songs in the crib, then patted down and even slept in the toddler bed. We all finally agreed that big Kindergarten boys didn't need help going to sleep, and now it's not a problem. #1 son still comes in to snuggle with us in the mornings, but only if it's still dark.
With boy #2, I'm making some of the same mistakes (like nursing to sleep. Oops.), but I'm also learning to let baby fuss to a small degree. I still really don't want to go the Ferber route, but if it's small, "I'm tired" crying, it's not that bad.
