At 11 weeks pregnant your baby now measures 4cm. They’re going to grow as much in the coming week as they have done in the previous eleven! Their brain, lungs, liver and kidneys, although minute, have all formed. They can suck, swallow and even yawn! Your baby can also ‘breathe’ amniotic fluid and urinate. Now that their fingers have separated, they will soon be able to open and close their fists and grasp things in the womb. All organ systems are functioning but will keep developing and maturing in preparation for birth. They’re already busy kicking and stretching, and their movements are more fluid.
