Our Baby This Week


18 Weeks


Well, the leg cramps, heavy belly and Braxton hicks have all started.The problem is that those all indicate Iím further along than we think I am.With the size of my belly and some other pregnancy symptoms that arenít appropriate dinner conversation, Iím starting to wonder if that is in fact the case.I guess weíll find out Tuesday.Thatís when weíll have the ultra sound and hopefully get to peak in our package.Timeís a ticking if you want to vote for a boy or a girl!Anyway, head to bottom, our baby is approximately 5 1/2 inches long (about the length of a large sweet potato) and he weighs almost 7 ounces.His blood vessels are visible through his thin skin and his ears are now in position and stand out from his head. Myelin (a protective covering) is beginning to form around his nerves, a process that will continue for a year after he's born.


You can email us with your vote for a girl (Hurray!) or a boy (Yippee!).Iíll post the results when we find out the sex through the magic of scienceó December 20th.

Note that, for the purposes of this chart, babies are measured from the crown (or top) of the head to the rump (or bottom) until about 20 weeks. After that, they're measured from head to toe.
