How does holding a newborn affect brain development?

If it affect's the parents brain by holding it. It affects it by practicing keeping him/her safe. it also affects it on how you will remember that moment when you first hold it. but the newborn will be affected by lets say...seeing its mother or father for the first time. it will remember there faces for their whole life. :>

It affects the brain devolpment with calastration on clatured brain cells 

Dialect is probably part of the answer
