Thanks to all that splashing in the amniotic fluid, your baby&#8217;s muscles are becoming stronger. He can now make a fist and bend his arms and legs. Meanwhile, your child can now open his mouth and press his lips together. You can&#8217;t really call it sucking yet, but it is starting to look a bit like it.    <\/p>\n<p>Your baby is now also regularly swallowing amniotic fluid. And because the kidneys are already working, your baby is also urinating small amounts. Incidentally, your baby&#8217;s waste products are regularly eliminated.  <\/p>\n<p>His limbs and internal organs have been formed. From now on, he only needs to grow and mature. That maturation is very important. Your child is ready in terms of structure, but cannot yet survive outside the womb.   <\/p>\n<h3>You<\/h3>\n<p>Your breasts are now nowhere near as sensitive as they were in the first three months. But they are probably still large. They may have grown a whole cup size. You really need a maternity bra that offers good support. A maternity bra is not only sturdy, but your breasts can also \u2018grow\u2019 into it.    <\/p>\n<p>The size of your breasts will increase even more in the coming months as the mammary glands prepare for breastfeeding. You may also already see blue veins showing through the skin, and your nipples are becoming larger and darker in color under the influence of pregnancy hormones. <\/p>\n<p>The amount of blood in your body also increases. This is necessary to meet the demands of the growing uterus and placenta. As much as one and a half liters is added: five liters becomes six to six and a half liters. A particularly large amount of blood plasma is produced.   <\/p>\n<p>Because you have more blood, your heart has to work harder to pump all that blood around. Your heart is now beating fifteen to twenty extra times per minute. You may already be leaking a few drops of milk from your breasts. That is completely normal and harmless. Usually, this stops again in the last few weeks before the due date.    <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Week 15 As long as a teaspoon Your baby The head is the size of a marble, the little fists&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":1653,"menu_order":0,"comment_status":"open","ping_status":"open","template":"templates\/flex.php","meta":{"_acf_changed":false,"footnotes":""},"class_list":["post-1818","page","type-page","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/verloskundigenrotterdamwest.nl\/en\/wp-json\/wp\/v2\/pages\/1818","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/verloskundigenrotterdamwest.nl\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/verloskundigenrotterdamwest.nl\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/verloskundigenrotterdamwest.nl\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/verloskundigenrotterdamwest.nl\/en\/wp-json\/wp\/v2\/comments?post=1818"}],"version-history":[{"count":1,"href":"https:\/\/verloskundigenrotterdamwest.nl\/en\/wp-json\/wp\/v2\/pages\/1818\/revisions"}],"predecessor-version":[{"id":1819,"href":"https:\/\/verloskundigenrotterdamwest.nl\/en\/wp-json\/wp\/v2\/pages\/1818\/revisions\/1819"}],"up":[{"embeddable":true,"href":"https:\/\/verloskundigenrotterdamwest.nl\/en\/wp-json\/wp\/v2\/pages\/1653"}],"wp:attachment":[{"href":"https:\/\/verloskundigenrotterdamwest.nl\/en\/wp-json\/wp\/v2\/media?parent=1818"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
