Your placenta has developed and is providing your baby with oxygen, nutrients, and waste disposal. The placenta also makes the hormones progesterone and estrogen, which help to maintain the pregnancy.</span><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/babyslideshow.html/" style="line-height: 16.8px;"><img class="right" title="Watch Your Baby Grow" src="https://kidshealth.org/EN/images/promos/PregCal-BabyGrow-enPR.jpg" alt="Watch Your Baby Grow" /></a></p> <p>By now, the baby's eyelids have fused together to protect the eyes as they develop. Once you <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/bringing-baby-home.html/">take your newborn home</a>, you might be wishing for those eyes to close once in a while so you can get some rest!</p> <p>Your baby might be able to put a thumb in his or her mouth this week, although the sucking muscles aren't completely developed yet.</p> <p><img class="left" title="Week 13" src="https://kidshealth.org/EN/images/galleries/PregCal-Week13-enGL.jpg" alt="Week 13" /></p> <h3>Your Body</h3> <p><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/momandbaby-slideshow.html/"><img class="right" title="" src="https://kidshealth.org/EN/images/buttons/PregnancySlideshow-Belly-enBT-1.png" alt="Watch your belly grow!" /></a>At your first prenatal appointment, your health care provider probably gave you a prescription for prenatal vitamins. Taking these supplements, in addition to <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/eating-pregnancy.html/">eating a healthy diet</a>, ensures your baby gets needed vitamins and minerals, such as <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/preg-folic-acid.html/">folic acid</a>, zinc, iron, and calcium, which aid growth and development. Talk to your <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/pharmacist.html/">pharmacist</a> about the best way to take your vitamins (such as whether they should be taken with food).</p>
