Your toddler is learning how to assert their autonomy and independence. However, with a limited understanding of the how the world works, they may end up feeling challenged and confused when things don’t go their way. As such, nearly 90% of toddlers will have the occasional tantrum (with the number and severity of tantrums peaking around age two, due to a surge in cognitive development). With undeveloped emotional and social skills, toddlers can express emotions such as anger or frustration by screaming, crying, falling to the floor, thrashing limbs around, hitting, kicking, throwing items, and in some children, holding their breath. But with insight and strategy, you can learn to defuse explosions and calm the farm.
