Learn as much as you can about infants. It takes time and practice to be a good provider. Also, there is no perfect infant. Infants are human. They have needs and feelings.
Infants look and act differently.
Some babies are born quiet. They may want to sleep all the time. Some babies are demanding and very active. Let each infant be himself or herself. Adapt to each infant's behavior instead of pushing the infant to be more like other infants.
