Latching Problem

My two week Old Newborn Latches on my wife But Will Stop Suckling After 5 Minutes. She Will Keep Crying (sometimes for as long as 20 mins) Until The she Finally Finds The Right Angle Or Position And Finally Latches Again.And most of the time she will not latch at all until we find the right position or angle for her. This applues sometimes to her bottle too. Is this normal?(edited)
