Parent A left 4 month old baby unsupervised in a baby bath (pic attached) which was on bathroom floor whilst they nipped across the landing to grab baby's towel from baby's room.
Parent B is appalled and thinks this was a serious lapse in judgement as they don't take their eyes off baby for even a second in the bath. Parent B thinks Parent A should have instead called them to get the towel.
Parent A thinks Parent B is overreacting and overly anxious, and is sure that baby was fine for the 20 seconds or so they were out of their sight.
Who is right here?
