The baby moves because it has arms and legs and the baby moves around a lot because it's growing and bones are developing..
Because they are alive. Do you wake up in the morning and stay catatonic for long periods of time? I highly doubt it. Babies move just like every other life with a heartbeat (kittens, puppies, tigers, etc.). Growing, stretching out, rolling over, all of these things are practice for outside the womb
It's a good thing .. i'd be concerned if it wasn't moving alot. Enjoy them Movements it's The one thing I missed the most after having my first 2 kids .
Umm...you should be happy.
