Is it wrong, now that I know I'm having a boy, to want ALL his shirts to say things like, "Mama's New Man," "I love my Mommy," "Property of Mom," ect?

I absolutely love all these things. I know you obviously can't put your mark on them forever but these shirts make my heart melt. I also love all the little rocker stuff since DH plays guitar. Now that I know the gender this is too fun.
Re: Baby clothes: Is it wrong...
no, it's cute and you're excited!
btw, did you see these jeans from gap? if i was having a boy i would have bought them already...too freakin' cute!

And they have some cute/funny maternity shirts as well... some of my faves are the baby with a mowhawk and rocker fingers in the womb (DH often sports one), the "Yeah; because telling me 'You're Huge' is going to make my day", and the no-touchy shirts.
I don't think it's wrong at all. Dress him cute while you still get to pick the clothes out.
P.S. Congrats on the baby boy Labor Buddy...I'm back to work now so I must have missed you posting when you found out!!!
YES I love those and I am going to get them as soon as I decide on a size range
Oh don't worry, by then I'll just take him to get his first tattoo, a big heart with Mom scrawled across it. LOL, DH would have a shitfit as neither of us have tattoosOh and I love that shirt site!
