I think I have one or two pictures of myself in pajamas as a small child, but my memory is that by the time I went to school I normally wore a nightgown. I don't recall calling it a nightie either. I think maybe my brothers had pajamas, to rhyme with llamas.
2. Favorite sleepwear put on your own little ones, or perhaps those you babysat? (Bonus points if you made it).
Well, I certainly don't get any bonus points here. My mother made a lot of our clothes, but I actually can't recall whether she made nightwear. I'd say my favorites for my kids were the feety pajamas (we did live in Minnesota after all) -- for some years at Christmas they got matching or coordinating ones. The last time for that was when SonShineIn was about 11 and the girls were 5 and 10 years younger -- he got a "manly" dark brown like a teddy bear and the girls' pajamas were pink.
3. How about today-do you prefer nightgown, pajamas, undies, or au naturel?
Still nightgown, although I do have a few pairs of pajamas.
4. Silky smooth or flannel-y cozy?
In winter, flannel or that brushed stuff that's a little lighter than flannel is my favorite. In summer, my preference is for light, smooth cotton, but that's not always easy to find so lightweight jersey has to be part of the mix.
5. Socks or bare feet?
