By now, your baby is happily crawling or scooting across the room, sometimes at speeds that make leaving delicate objects on the floor a dangerous idea.

Your baby may even have taken some tentative steps. But if your infant still hasn’t crawled or cannot sit up unassisted, you may want to talk with your pediatrician about his or her developmental milestones.

Below is a list of red flags to know about your child’s development. Contact your child’s doctor or nurse if you see these signs of possible developmental delay, especially if you see your child regress in skills or development.

It is important to remember that this is not a definitive list, and babies develop according to their own schedules. If your child has not reached a particular milestone, there may be nothing to be concerned about, but it’s a good idea to make an appointment.
