Your baby at 19 weeks

19–20 weeks

Over the past two weeks, the baby has grown very much. Perhaps, the most important thing that can be said now about its development is that it is already possible to determine with ultrasound whether a boy you have or a girl. IMPORTANT: when you learn the sex of a crumb, do not cry out loud and ask others to abstain from that. Look how baby ears grew, as well as the level of awareness, so now the kid is afraid of loud, sharp sounds. But you can dance though: he will support you with joy, he adores activities. Even his head can already lift and rotate 180 degrees! And if you remember that he weighs more than 0,7 lb, you will certainly feel this internal cheerleading.

By the way, the movements of your baby cease to be chaotic, they become much more conscious, the kid is getting smarter every day. This worries him so much that his heart is forced to develop actively: now it’s knock can be heard with a conventional stethoscope, brought to the belly.

Something that is not obvious in the picture above, but still significant: fingers already have little nails, and there is a unique pattern already on the pads of his fingers, the whole body is covered with a fluff of lanugo. Even the face. After birth, he will lose this protective puff, so feel it now: there is a fluffy cutie inside you.
