Normal... If it makes you feel better, we just had a similar experience. My cousin brought her 15mo old over for her first visit (they live out of state). They were in the area for a month, staying with cousin's mom most nights. During that time, no one could get near her without blood-curdling screaming! Mom and baby went to bed at the same time, got up at the same time, and Mom wasn't even allowed to use the bathroom without baby following her (or freaking out). It was like that child had a sixth sense for when mom went 3 feet and 1 inch away!
