How many teeth does a baby get?

That's probably something I should know, either from junior high health class or because I'm the mom and moms know stuff like that. The reason I ask is because Henry is trying really hard to cut his first tooth and it has thrown our happy home into disarray. I'm wondering exactly how many more times we have to do this.

At Henry's three month check up our pediatrician said his gums looked a little swollen and that she wouldn't be surprised if he had a tooth soon. Fast forward three and a half months and he's still toothless. I thought he was teething on and off for three months but I didn't know what teething was. It reminds me of being in labor. Yes, I was in labor at 10 a.m. and it did hurt, but I wasn't really in labor until about 8 p.m. and Henry wasn't born until the middle of the night. Right now I am anxiously awaiting the birth of Henry's first tooth.

I'm not sure how much more low-pitched whining I can take. I feel like he has regressed to being a newborn again, up screaming in the middle of the night and all. Except I am no longer in shape for the up-all-nights. I had a brief but glorious taste of sleeping through the night and I want it back. Henry's has regressed to eating around the clock and is so far not a big fan of solid food. I have visions of bringing my nursing cover to the cafeteria everyday when he's in kindergarten and he still doesn't have any teeth and still won't eat anything but breastmilk.
