Butterflies fluttering inside you, or bubbles – that’s how many women describe feeling the foetus moving inside them for the first time. It usually happens around this time of the pregnancy. However, with a first baby, you may not feel it until 25 weeks – and with a second baby it can be as early as 16 weeks.
Apart from swimming around, the foetus is now growing eyebrows and eyelashes, and nails on its fingers and toes. The senses of taste and touch are developing, and the eyes are properly developed too. With a lot of medical care, foetuses born at 24 weeks can sometimes survive.
