When someone ask to Budha What's Happiness? He replied with very politely when you control your greed and satisfy with whatever you have,means you are the happiest person.
He also unaware about the world and its charismatic invention and came into this world where every one strage for him. Now there are two way to either he born with silver spoon or in very vulnerable family, after spending some course of time with family he identifiy faces like parents ,grandparents or relative but he is totaly unaware about finance status or economy background of family he laughs more loudly ,He cried more.
Inital stage of children are same whether they are rich or poor,on that stage family play very crucial role,wealthy family provide them extra facilties on other hand it is too difficult for poor to manage bread for twice in a day therefore it is cause of6 malnutrition or other serious problem in their children I assume that main cause of malnutrition is only lack of food but also thought,behavoir of family and environment as well as child grow he become blunt and far away from education there he dominated himself these domination turn them towards sorrow,negatively and boring life.
When I was travelling from Kanput to Gonda in general wagon(Dibba) I met a couple who were taking good sleep on the floor of wagon They have no intrest in Birth while I was standing and my an eye was on those seaters who occupy seat I am waitning for that moment how early they stand and I sit there my whole focuse only those birth while they lie and look like to the most relaxible couple in the world.
On that day I feel that happiness can't buy it depends on your mindset how you treat you have to find it anywhere.
