Why does baby kick?
Baby is sensitive to all her stimuli: changing your position, sitting too long in front of the computer, taking a shower or bath, being hungry [1], and even changes in the lighting around you [2] can make baby respond with kicks, jabs, and turns. By the second trimester, baby's movements become stronger, and by 20-24 weeks, when she develops hearing, the muffled sounds can cause baby to throw a punch or two [3]. Babies also often start to move more actively after 9 pm due to changes in mama’s blood sugar [4].
Kicks and punches are no reason for concern. As the weeks progress you will become familiar with her movements. If her movements change in nature and you feel worried, you can consult your doctor. For example, if the baby pushes too hard for an extended period of time it could be a symptom of a lack of oxygen, in which case it is best to see a doctor immediately [5].
