13 Weeks...

Your babies each weigh about 1/2 ounce and are between 2.5 and 3 inches in length. Their digestive tracts continue to develop as tiny villi (hairs) form inside their intestines to aid the digestion of food, and their pancreases have begun producing insulin. All 20 teeth buds have formed inside each of their mouths; but, of course, the teeth aren't visible yet. (That would make predicting orthodontist bills way too easy!)



*Your infant is about 2.91 inches (7.4cm) and weighs around 0.81 ounce (23gm) - This is about the same weight as 4 quarters.
*If you could peek in again you may spot your baby as he begins to practice inhaling and exhaling movements
*Eyes and ears continue to move and develop
*Baby's neck is getting longer, and the chin no longer is resting on his chest
*Her hands are becoming more functional - Your baby may find it comforting to start playing with her fist.
*At this point all nourishment is received from the placenta
*On your next doctor visit you should be able to hear heartbeat with a Doppler by now - (Don't worry though if you can't, the heartbeat can be confirmed through U/S). Your baby's heartbeat is much rapider than your own and may remind you of the race towards birth that he is running!
