Some things I have observed and learned since being pregnant: Measuring how far along you are in your pregnancy is similar to measuring a child's age. When you ask a child how old they are, the response is often 5 and a half. Or 3 and a half. If you say "Oh really? You're THREE?!??" They'll say "NO! Three AND A HALF!" That half part is very important to them. Well excuse me, I am not 18 weeks pregnant, I am 18 and A HALF weeks pregnant. That half week makes a huge difference to me and my baby's development so you better accept and acknowledge that for yourself as well. Along those same lines. Measuring how far along you are in pregnancy makes absolutely no sense. Everyone knows that women are pregnant for 9 months. Or 40 weeks. Unfortunately our calendar is not based on women's cycles, so one month does not exactly equal 4 weeks. So usually I would think oh, I'm 8 weeks so I must be 2 months. But could 2 months not come around until 9 ...
