Ten things I didn't know before I was a dad

Some of them I did know once, but had forgotten. Also there are far more than ten, but here's my 'starter' list:
- Mothercare does actually serve a useful purpose
- singing nursery rhymes can be fun
- the joys of gurgling
- how wonderful my son smells
- work isn't as important as I thought
- just what a difference a day really can make
- prams don't fit into cars as easily as they should
- the expression 'sleeping like a baby' is an oxymoron
- what miraculous stuff breast milk is
- how great it feels when people say 'what a beautiful baby!'


Anyone care to add their own?
