Sleeping pattern changes at 1YO

Since her fever over the last weekend from her 1YO vaccination, my girl will suddenly wake up & sit up crying hysterically from her night sleep and only stops when we bring her over to sleep on our bed. Once she’s asleep for us to transfer her back to the cot, she’ll go hysterical again. The kind of cries is like she’s hurt badly or something. It’s so disturbing. Anyone has similar experience could share y she’s behaving this way? #advicepls #tired
