What I learned yesterday about being pregnant:
Just because you were capable of dragging two big, heavy, expensive books
around in a bookstore for an hour or more of browsing BEFORE you got
pregnant doesn't mean you can necessarily hack even 45 minutes of it at 15
weeks.
So, if there are enough copies of the books that they won't all fly off
the shelves in the next hour, do the rest of your browsing/shopping, then
go back for them just before you want to check out. (The extra trip up
and down one flight of stairs is nothing compared to what lugging the
books around will do to your back....)
(On the bright side, we're pretty much set for presents for my
father-in-law, which is unheard of at this point in December unless we'd
ordered shirts for him over the summer.)
