Yes. From birth to 6 months, baby’s need for breastfeeding diminishes. About the time they start crawling around on the floor and feeding themselves with their hands is also when they may lose interest in sucking. Older babies need less milk, so their appetite drops too.
It's important for older infants to nurse less often than younger ones. So they don't go hungry between feedings. But by 6 months old most babies are eating solid food three times a day. And usually only nursing one or two times at night for sleep time or comfort needs that's perfectly normal development.
