Oh my God, boys are effing amazing. I have 2 of them, a 5 year old and 3 year old.
Every day, when the helper picks them up and takes them to the park after school, they come home covered in sand and dirt and present me with a gift. DS1 generally picks me a flower and DS2 often gives me a rock. Although the other day he gave me a baby hermit crab.
They are the funniest, silliest, grossest little blighters in the world and I love seeing them covered in mud, and wrestling. They make jokes out of farts, talk about their willies all the time, and have bottomless pits for tummies.
And at night, they climb into our bed and I wake up with a little, chubby 3 year old hand rubbing my face and a whispered "I love my mama" - seriously, it's so bloody cute.
In fairness, I don't think it would be ANY different if they were girls, they would still be wrestling, making fart jokes and getting covered in dirt but I can only speak from my experience of my boys.
They are seriously fantastic - congratulations!!
