If your baby, infant or toddler is inconsolable and has cried for more than two hours
If you’ve used substances of abuse during your pregnancy
If the crying might be related to an injury or a fall
If there are signs localizing a possible source of pain: an unexplained bruise, not moving an arm or leg, fiddling with an ear, a bulge in the groin area, the passage of hard stools, diarrhoea or a testicular swelling.
If there are symptoms suggesting a systemic illness or infection: fever, rash, not drinking or feeding well, being less active than usual, or not responding in the usual way.
If there are any of these danger signs: vomiting; bulging or sunken fontanel (the soft area on top of a baby’s head); signs of dehydration (dry mouth; being thirsty; absence of tears when crying; sunken eyes, no urine/wet diapers for 4-6 hours); a distended tummy; bloody bowel movements.
