Your baby now weighs about 2 1/2 pounds (like a butternut squash) and is a tad over 15 inches long from head to heel. Her muscles and lungs are continuing to mature, and her head is growing bigger to make room for her developing brain. To meet her increasing nutritional demands, you'll need plenty of vitamin C, protein, folic acid and iron. And because her bones are soaking up lots of calcium, be sure to drink your milk or find another source of it-cheese, yogurt, or enriched orange juice. This trimester, about 250 milligrams of calcium are deposited in your baby's hardening skeleton each day.
TMI time! Did you know that my baby girl drinks and breathes her own pee?! EWWW! Yes, she whizes in her amniotic sac and then turns right around and inhales that amniotic pee-filled fluid! Fortunately, her urine is STERILE. That's part of the reason that I need to drink LOADS of water-to give my baby girl a purer, less urine-based drinking/breathing fluid. Loads of water, fresh fruit and veggies=less nasty drinking water for my sweet lil' lady.
