Week 16 is here… It is hard to believe that four months have gone by! K continues to feel better and we have seen a marked increase in her appetite (the extra ice cream is for the baby!). We are also beginning to see the Linea Nigra (latin for dark line) on her belly. This is the dark line that begins to show during the second trimester that runs vertically down her belly. Apparently, scientists don’t fully understand this phenomenon but think that it is linked to increased levels of estrogen. On a side note, lots of people think the presence of this line is linked to the baby’s gender… though every source we have read refutes this claim!
