Not to be a party pooper, but it can get much worse.
I have 2 boys, 17 months apart, and the craziness that ensues.
BTW, the cleaning of the pee does not get any better. Once they get potty trained, then you have the added bonus of cleaning the pee from the bathroom. :)
It took me 6 weeks to figure out how the pee was getting on the doors of the vanity that is across from the toilet. <shakes head> LOL
