Nine months and ten days (field varies) When a baby is born from the womb, it is very small and helpless. Gradually their body and energy develop. Two forms of this development catch our eye. The first can be called physical development, the second is educational development. The child grows up with the development of both body and mind - in many ways these two developments are interdependent.

Below is a timeline for baby development. Needless to say, while this schedule is fairly accurate - it does have a few twists and turns for different children. However, based on this schedule, the child's family will be able to understand at least a little bit, whether their child is developing properly.
