She will therefore be a healthier, sturdier child. He won't feel safe, no matter where he is. Instead of exploring his world to learn about it, he will either anxiously hang back or recklessly throw himself into it in search of the love he knows is missing. Habitual stress will weaken his immune system, and he will therefore be more likely to have frequent or chronic illnesses. Love isn't just something nice that makes us all feel good.
Love is vital.
Babies who are not touched and cuddled may sicken and die. If they don't die, their mental development can be delayed or even irrevocably arrested. Small children who are touched with affection are less inclined to aggressive behavior, and less likely to grow up with violence in their lives. A lot of people will say that the only way it can be done is for mothers to stay home with their children, and a lot of mothers are choosing to set aside their careers for a while to do that. As a family therapist, I'm biased toward a child having an at-home parent for the first five or six years at least, for at least half a day.
