At five months old, Umar was a healthy, active baby who was growing in line with his developmental milestones, and already able to roll over and turn. Once his mother returned to work after exhausting her maternity leave, Umar was sent to the same childcare centre as his brother. There was no reason for Umar’s parents to doubt the centre’s ability to care for him as their older son had been there for more than a year. However, one morning about two months ago, Umar’s mother received a phone call informing her that her infant was having difficulty breathing.
