Many new moms think their babies just kick in the womb, but this ultrasound shows that there are other movements going on that we might not know about.

This viral video shows a very active baby who uses its legs to jump in the womb. Take a look for yourself:

What do pregnant women feel?

Moms love the feeling of their babies moving inside them. These movements can start out tiny and feel like butterflies, waves, a twitch or a nudge. Later in your pregnancy, you'll start to feel the baby moving more forcefully, and it can be uncomfortable at times.

When does the mom start to feel movement?

According to What to Expect, "Most women feel the first fidgets and squirms ... between weeks 14 and 26, but generally closer to the average of week 18 to week 22 (though variations are common)."

If you don't feel your baby move after that time frame, it's best to consult your OB/GYN.

A mother should always be attentive to her baby's movements, especially if the movements are dramatically decreased. This can be a sign that there is something wrong with the baby.
