4 months: The baby has been busy growing and is now about 4" long (100mm). The bones are forming and growing to help support the new muscles. The baby is big enough now for the mommy to feel many of it's movements. This is an exciting time for the mommy as she begins to "dance with her baby"

5 months: We're halfway there. The end of the 20th week is the halfway mark to delivery. The baby is now 8" (20cm)in length and 8 oz (225gr). The baby dances and kicks around a lot now and the mommy's tummy is being stretched as the baby get bigger. Mommy and baby are both waiting for the lungs, digestive organs, and skin to finish growing. They're both getting excited about the big day!
