Week 18 of pregnancy: Mother and Babies development and changes


18 cm

Pregnancy Milestone: Four Months In

Entering the fourth month of pregnancy marks a significant milestone, with just five more months to go until your little one arrives. Your baby is now the size of a sweet potato, and those subtle flutters in your belly could very well be their movements. Let’s explore more about your baby’s development this week.

Baby’s Growth: Rapid Progression

At 18 weeks pregnant, your baby is approximately 18cm long and growing rapidly. They are settling into a daily routine and have begun developing sleeping habits. Additionally, their unique set of fingerprints is starting to form, adding a personal touch to their growing identity. For expectant parents of boys, this week brings a clearer view of their genitals, making them more distinct and easier to see on a scan.

Managing Dizziness: Common Pregnancy Symptom

Dizzy spells are a common occurrence at this stage of pregnancy. They stem from the increased volume of blood in your body, requiring your heart to work harder to cope with the extra load. Additionally, your growing uterus may exert pressure on blood vessels, leading to faintness. Taking frequent rests, maintaining a healthy diet, and eating small, regular meals throughout the day can help stabilize blood sugar levels. Be cautious not to rise too quickly and focus on consuming slow-release nutrients found in oats, fruits, and vegetables rather than opting for quick sugar fixes.

Sensing Baby’s Movements: The Fluttering Sensation

If you’re feeling what seems like butterflies in your stomach, it’s likely your baby’s movements. This sensation typically occurs between weeks 16 and 20 of pregnancy, though full kicks won’t develop until later stages when your baby is more substantial.
