One of my favorite stories was when Nick was born. He was born at home and my mother lived a few blocks from me. My husband called her just seconds before Nick was born so she walked in the door about 20 minutes after. I was nursing him and cooing over him because I thought he was the most beautiful baby I'd ever seen!
I handed him to my mother to diaper so I could clean up and to let Greg strip off the sheets to the clean set I had underneath. As I was getting ready to get back into bed - I realized I hadn't actually checked to make sure he was a boy! (I had had an ultrasound the month before which indicated he was a boy.) I whipped around to mom, who was holding him in the rocking chair and said "OMG! Check and see if he's really a boy!" She said "No need" and pointed to the wet spray all across the front of her shirt. Apparently the minute she tried to diaper him, he peed all over her!
