Had a son. I learned that the whole "they grow up so fast! blink and they're not even babies anymore" thing is not a cliche at all. Time has flown and it is blowing my mind.
Just had my son four weeks ago. What a crazy ride it has been already. I went from 'this is wonderful' to 'maybe this was a mistake' to 'I don't want him to grow up anymore' all in that short time span. It's amazing. Would love to swap notes :D
