Answer: Hello! You should feel your baby's first movements, called "quickening," between weeks 16 and 25 of your pregnancy. If this is your first pregnancy, you may not feel your baby move until closer to 25 weeks. baby's movements as butterflies, nervous twitches, or a tumbling motion. At first, it may be hard to tell whether your baby has moved. Second- and third-time moms are more adept at distinguishing those first baby movements from gas, hunger pangs, and other internal motions. By your second and third trimesters, the movements should be more distinct, and you'll be able to feel your baby's kicks, jabs, and elbows.
