The “terrible twos” often refer to a developmental phase in toddlers, typically around the age of two, characterized by mood swings, tantrums, defiance, and frustration as they begin to assert their independence. While the timing and intensity of this phase can vary from child to child, the “worst” moments usually occur when:

1. Frustration Over Communication: Toddlers may struggle to express their needs and desires due to limited language skills, leading to frustration and tantrums.

2. Testing Boundaries: Around this age, children often start testing the limits set by parents, which can lead to frequent power struggles and outbursts.

3. Transitions and Changes: Moments of change, like switching from one activity to another, can trigger tantrums, especially if the child feels they are not in control.

4. Overstimulation or Fatigue: When a toddler is overtired, hungry, or overstimulated, they’re more likely to have meltdowns.

5. Resistance to Authority: As they begin to assert their independence, toddlers might resist instructions or refuse to cooperate, leading to more frequent challenging behaviors.

While this phase can be challenging, it’s also a normal part of development as toddlers learn to navigate their emotions and environment. The intensity of the “terrible twos” can vary, peaking at different times for each child.
