After about 20 weeks, you should feel your baby should move every day, but there's a wide range of how much activity is considered normal. On some days, your baby may seem like the Energizer bunny, while other times you may be less likely to notice every little kick and wriggle. But even during his downtime, your baby is probably moving more than you realize -- it just may be so subtle you're not aware of it. And many moms-to-be who work or care for other kids are so busy that they don't notice their baby's movements until they sit down to rest for a few minutes or lie down in bed at night.
If the lack of movement on your baby's quieter days leaves you feeling concerned, you can reassure yourself with this simple test: Eat a light snack and then lie on your side or sit very still for an hour. You should be able to count your baby moving or kicking between six and eight times within that period. If not, give your doctor a call.
