Even some babies who are disabled seem to improve best when various systems receive increased stimulation. And it is also true that the environment can indeed influence the development of a child's body, brain, emotional and social development. But this does not always translate into a stimulating environment. Sometimes a baby needs less stimulation. Sometimes too much can be as detrimental as no stimulation at all.
Some babies are easy to care for.
Others might be irritable. Some like to cuddle, others do not. Some babies' bodies are soft, other bodies are stiff and rigid. It is important to point out that in none of these instances are the babies bad. Babies cannot help who they are and how they behave at such an early age.
