my mom is stalking me

We left my parents house on Sunday. Starting on Monday evening until I called her back Tuesday evening, here are the missed calls from my mom:

7:40pm
9:51am
10:32am
12:53pm
1:58pm
2:06pm
4:28pm

Why was she redialing me so often? She had come down with a cold and was panicked that she had gotten the baby sick. I'm not sure if she thought that talking to me on the phone would somehow prevent the baby from getting a cold or make him all better or what.
