They keep getting more and more expensive as they grow.
The cheapest period is for the second kid, after the age of 2 (my second daughter) -- out of diapers and reuses clothes from the older one...
However, as they get more expensive, you adjust and give up on some things that you could afford when dating...
For example, I always wanted a 5er, but am happy with the 3er.
My wife wanted the Q7, but Odyssey does not sound that bad after all
