Your breasts don't have to feel 'full' in order for you to have milk ready for your little one. I don't pump (my 5th is 5 months old)...actually I don't own a pump, don't need one. When your baby's appetite changes, your breastmilk will follow the change. Each baby has their own way. My youngest has changed to where he doesn't want a morning feeding right when he wakes up.
That's wonderful that your baby sleeps that way at night! My last two children would not sleep in their crib during the night, but did some throughout the day. But only during the day after they were 3 months and older. I always held them whether in a sling or just held them while they were sleeping during the day. They eventually get to their crib during the day. It just takes a while. They were bunched up in your for quite a long time, they still want their momma. You sound like you are doing great!
