Our daughter is five months old now, and slowly being able to actually play with her and getting her to laugh is so much more fun than the loaf of bread that just stares, poops, cries and drinks milk that she was in the first two or three months. I think the age that I'm looking forward to the most is around 4 years, when I'll be able to explain stuff to her, visit the zoo and whatnot. I read once that nobody is as big of a fan of you as your four year old.
