When your baby is first born, it can seem impossible to imagine them playing games or sitting up, let alone walking and talking. As each month passes, you will notice more and more developmental changes (or milestones) as they learn to coordinate their fingers and hands, to control their voice and to interact with people and their surroundings. Watching your baby's development is enjoyable and rewarding as a parent. Understanding the broad definitions of 'normal development' and the differences between every child is also important. It helps you to identify the rare cases where delayed milestones might be cause for concern but it also empowers you to enjoy your child and their own rate of development rather than worrying unnecessarily about how they compare with others.
