While most babies tend to show progressive development in the form of beginning to manifest a personality of their own, laughing, cooing, being more responsive and perhaps learning to clap, it is important that you, as a parent, do not get too carried away with what is considered 'normal.' Not all babies are the same and while most will achieve all of these milestones by the 14th week, your baby may genuinely be a late bloomer and it does not mean that they will be a late bloomer for life. Try and not compare your baby to other babies, trust the process, engage with your child and reach out to your doctor for double assurance.
