1. If the thermometer reads 48 degrees at 10:30 at night, but your husband says that the t-shirt material your child is wearing to bed, without feet in it, and without socks (because your child doesn't own any) is warm enough, your child will wake up at 2:17 a.m. wailing. When you pick him up, he will resemble a popsicle, but he will instantly go mute when he realizes that your guilt has guaranteed him sleep in between mom and dad for the rest of the night. Said guilt will carry over to his being allowed to push mom to the last 4 inches of bed so he can have lots of space.
2. Your family's reputation will proceed you and will become your own. On the way to Costco with my father-in-law (just the three of us), he stated that if I planned on nursing the baby in Costco, he would like to stop on the way and buy a t-shirt that says "Grandpa" on it. I told him that if I had to choose between a screeching baby and exercising my legal rights under Idaho law, I choose the option that results in silence. He agreed wholeheartedly.
