Early in your pregnancy, you may just feel a few flutters every now and then. But as your baby grows -- usually by the end of the second trimester -- the kicks should grow stronger and more frequent.
Studies have shown that by the third trimester, the baby moves about 30 times each hour.
Babies tend to move more at certain times of the day as they alternate between wakefulness and sleep. They are usually most active between 9 p.m. and 1 a.m., right as you're trying to get to sleep. This surge in activity is due to your changing blood sugar levels.
Babies also can respond to sounds or touch, and may even kick your partner in the back if you snuggle too close in bed.
