How is Your Baby Growing at 18 Weeks?
When your growing baby reaches 18 weeks, their nervous system is developing rapidly. The nerve cells are firing and this causes lots of movement, which you’ll definitely be able to feel (it will feel more like fluttering in your stomach as opposed to true movements at this stage).
The brain is also rapidly growing and new neural connections are being made. The eyes and ears are receiving signals from the brain and they continue to react to lights and sounds.
