Why babies cry can vary widely, but hunger, fussiness, wetness and being uncomfortable or tired are all reasons he’ll try to communicate with you by crying. And while some babies may cry more than others, they can eventually grow out of it.* So be patient, soon enough those tears will turn into smiles.
Why is my baby crying: The crying curve
Baby’s crying can follow a developmental pattern during the first three months of life – this pattern is referred to by many healthcare professionals as “the crying curve”1,2
- According to the crying curve, most babies’ crying begins to increase from 2-3 weeks of age, peaks around 6-8 weeks of age and then begins to gradually decline as they approach 12 weeks of age.
- Crying tends to occur more frequently in the evening, but can also occur throughout the day1,2,3.
* Speak to your healthcare professional if your baby’s crying is accompanied by fever, vomiting or diarrhoea, if you feel there is a significant change in behaviour or could be due to an injury.
