Pregnancy Calendar - Week 18
Your baby's ears are fully formed this week and she can actually hear you now. The process of your baby's bones hardening (ossification) begins this week. Your baby's senses of smell, hearing, and sight are all developing now, and myelin (which makes nerve cells connect faster) coats all the her nerves. Baby is now about 16cm long.
You may feel a ‘flutter' in your tummy around this time. You may not even notice it, or you may put it down to digestive juices, but it's actually your baby moving. If you don't feel it yet, don't worry, some women don't feel movement until 20 weeks.
