At which week you manage feel baby's kicks/movement? What are the factors that contribute to the detection of the movement as some mummies they are able to feel earlier compare to others?

I felt my baby's first movements at week 16, which is pretty early for a first time mother. It could be due to the fact that many mothers mistake fetal movement as gas or cramps. This is also why second or third time mothers tend to notice fetal movements much earlier as they are likelier to distinguish fetal movements from regular abdominal movement. http://pregnant.sg/articles/first-baby-kick-in-stomach/
