Breastfed babies and sleep

Emily

My 5 week old has been difficult in the middle of the night. When we initially put him to sleep he will sleep in his rocker next to us for a few hours. Then when he wakes up I feed him and change him and when I put him back in his rocker he wakes right back up and wants to be on the boob. The past couple nights ive had to basically be a pacifier for him all night and I hate it! How do I just feed him and get him to stay asleep in his rocker without being on my boob all night?!
