But these 2 quotes sum up the experience of mothering them daily, quite well:
"You are worried about seeing him spend his early years in doing nothing. What! Is it nothing to be happy? Nothing to skip, play, and run around all day long? Never in his life will he be so busy again." ~Jean-Jacques Rousseau, Emile, 1762
Worry, and 'busy, busy, busy' - it's so intense when they are little... They just have to be on the constant move, and you have to keep up! And, we have to sort out the good advice and "studies" from the bad and/or irrelevant. Kids learn through play!
Next Quote: "There was never a child so lovely but his mother was glad to get him to sleep." ~Ralph Waldo Emerson
