Babies conceived during winter months may be more likely to have learning difficulties

A new study suggests that babies conceived in months with less sunlight may be more likely to have learning difficulties due to vitamin D deficiency. Our midwife Kate tells mums-to-be to not to worry but to keep taking vitamin D supplements.

Vitamin D supplements.


New research from the University of Glasgow suggests that children conceived during winter months may be more likely to have learning difficulties. The study links low vitamin D levels in mothers who conceived between January and March, to children with conditions such as dyslexia. While this research reinforces the importance of taking vitamin D in pregnancy, we would encourage Mums-to-be who conceived in winter months not to worry.

Our midwife Kate explains why:

“The cause of learning difficulties is complex and poorly understood, there are many factors which may contribute to whether a child has learning difficulties or not.  We do know that having sufficient levels of vitamin D is important and pregnant women are advised to take a vitamin D supplement throughout pregnancy and while breastfeeding.  If you have limited exposure to sunlight, have a high BMI or a darker skin tone then you may need a higher dose of vitamin D; have a discussion with your midwife or GP if you think this applies to you.”
