I can imagine very well what you mean, by ‘looking at the world through a child’s eye’
First we grow up as children. Then, later (always never early enough) we become adults – and everything changes !
You cannot afford to do stupid thing anymore, cause that would be called ‘mad’ (it’s ok if you’re a child though).
Suddenly you have to take life serious (that is what everyone expects).
But what about this ‘grown-up’, after he/she comes home from work where he/she was behaving very, very adult … sees his/her small children who expect him/her to spend some quality time with them ?
Have you got the picture too where the adult becomes a child again (to be on the same level) at least for a short while ?
So, every adult has the capability of being a child, actually it stays part of everyone’s life until we die.
It is a part of us. Yes, even if some adults consider themselves superior over others. I call them ‘Presidents of the Universe’, hehe. (That is sarcastic) :-)

Coming back to the ‘seriousness’ expected from adults, I think that goes too far sometimes.
That’s when you feel how relaxing and releaving it is going back to childhood again. Escaping from the pressure of expectations.
Children are excepted from adult commitments.
Then, a ‘new/old’ world opens, and so does the point of view. (Explanation for what you wrote earlier)

Long story – short sense: I think nobody should ever amputate him-/herself from the child-part of him/her just because our society likes you to adapt.

Besides this, I think your pictures are very, very lovely!
