You know you have a boy when.....

[Cassie]

.....when they discover their penis and give you the biggest grin at their new discovery!

.....when they love to rip things up and leave mess all over the house!

.....when they are very interested in turning wheels and opening and closing doors!

.....when they 'read' their cloth books while filling their nappy!

.....when they get bored and then crack it when you take them shopping!

[werntonb]

...when he falls asleep on the couch watching TV just like Dad does (2 days in a row now after not having his day time sleep)
...when he makes the Tim the Tool Man "macho" sounds just like his dad

Here, I have noticed that my wife doing the same. She is like that. Congrats for the DAD and sooner DAD.

these are too funny!

When your little guy can hear a plane and points up to the sky before you even notice the noise

During shower/bath they just like to sit there with one hand on their willy

They fart, catch your eye with a sly little grin and laugh

EVERY trip in the car whether it's to the local shops or hours away, it's filled with "Hath! Hath!" and if you don't join in he just gets louder and louder! (Moo's word for trucks)

[MrsFabuloso]

You're searching for him when the thunderstorm begins only to find him out in the puddles fully clothes and soaking wet, throwing mud in the air rejoicing that 'it raining mummy, it raining!'
He plays with his penis anytime he has his nappy off and thinks it's hilarious when he joyfully informs you 'it weally big now mum'
He eats his vegemite sandwitch using the laptop as a plate (whist he watches Mickey Mouse- multitasking, right??) and then licks the vegemite off the touch mouse pad

[sconeonamission]

DS proudly shows off that he can wee "just like dad" with NO HANDS!
"Faster Daddy! Faster!"
"You're a hoon, Daddy!"
First few notes of music = "TOP GEAR!!" And will quietly watch the whole thing.
Everything is a car, truck, train and makes appropriate noises.
He can see things before I can see them (a green Kombi ages up the road, a tiny car in a busy picture etc)

I'm sure there are more!

...when flies eye's aren't the one's found on flies...

[~me~]

When your little princess thinks their brothers penises are like an old fashioned pokie machine where you just have to pull at all cost

[Doodlebug]

When you're at the fireworks with your parents and their friends and your ds (4yrs at the time), counts to 3 then gives his willy 'time out' coz it won't "sit down and behave"! Said in a loud voice so EVERYONE around can hear!!!!!!
