The baby’s lungs continue to develop until he/she is born. Turthully, they’re already capable of working, but this will only happen during that long-awaited cry in the birthing room that’ll make you emotional and happy. The amniotic liquid, which was translucent, is now more opaque and milky due to the vernix caseosa, the viscous, waxy biofilm that coated the baby and has started to come apart. New layers of skin and the maturing of the brain put the finishing touches on your little work of art, which soon you’ll be able to hold in your arms. The normal weight for a newborn varies between 2,5 and 3,8 kgs, while the length is usually between 46 to 45 cm.
