Sleep training / night feedings?

Cynthia

So, I have a 4 1/2 month old daughter and I recently moved her to the crib. We were co sleeping. I breastfed about 3-4 times a night. She doesn’t mind sleeping in the crib, but she does wake up (sort of) just to feed. How can I start weaning her off of night feedings? Is she too young?
