The last 4 days, my daughter (22 months) has been waking up from nap, and within seconds she is screaming bloody murder! I have to run into her room and console her and it takes 5 minutes to calm her down. It'd only been at nap time so far, but this morning she woke up after 12 hours of sleep and just screamed and cried sitting behind her door.

Normally she wakes up and talks to her little animals and is happy as a clam, so I'm not sure where this is coming from. She has a lamp that she knows how to turn on, so it's not a fear of darkness.

I just don't know if this is normal or if this has happened to anyone else?
