All pregnant women should start this at 28 weeks of pregnancy.
Even though you may feel your baby moving well before this, we still recommend waiting until 28 weeks to start doing official fetal kick counts. While you may notice days where your baby is more active before 28 weeks, in general it is not recommended to do official counts until after this time period because the movements can be inconsistent until then. This can lead to unnecessary worry and anxiety.
