A Closer Look at Week 14

Welcome to the second trimester! Week 14 marks the beginning of what many parents consider the most comfortable phase of pregnancy. Nausea is typically fading, energy is returning, and the risk of miscarriage has dropped significantly. Your baby is now the size of a peach and is developing one of the most charming abilities so far: facial expressions.

Thanks to increasingly sophisticated brain impulses reaching the facial muscles, your baby can now grimace, squint, and frown. They might furrow their brow or purse their lips in response to internal stimuli. These expressions are not yet conscious or emotional — they are neurological practice runs — but they are a fascinating sign of how rapidly the brain is developing connections to the rest of the body.

The neck is growing longer, separating the chin from the chest and giving the head more range of motion. Your baby's body proportions are slowly beginning to normalise, with the body growing faster than the head. Fine, downy hair called lanugo is beginning to cover the skin, helping to regulate body temperature and hold the protective vernix coating in place.

With nausea subsiding, you may notice a significant increase in appetite. This is your body's way of catching up on the calories and nutrients it struggled to absorb during the first trimester. Focus on nutrient-dense foods: lean proteins, iron-rich leafy greens, calcium from dairy or fortified alternatives, and omega-3 fatty acids from oily fish or supplements. A good pregnancy pillow can make a significant difference to sleep quality at this stage, especially if you are adjusting to sleeping on your side rather than your back.
