It is very common for toddlers around 21 to 24 months to go through a phase of bedtime resistance, often wanting to play instead of sleep. During this phase, focus on maintaining a firm, consistent routine, and stay calm—even if they cry or protest loudly. Many parents find success in remaining in the room while minimizing engagement, such as acting as if they are sleeping, to avoid power struggles. If the protest is severe, some parents have found that avoiding 'checking in' too frequently helps the child settle faster.
