Prague Spring (1968)

The Prague Spring was a period of political liberalization and mass protest in the Czechoslovak Socialist Republic. It began on 5 January 1968, when reformist Alexander Dubček was elected First Secretary of the Communist Party of Czechoslovakia (KSČ), and continued until 21 August 1968, when the Soviet Union and most of Warsaw Pact members invaded the country to suppress the reforms.

Warsaw Pact invasion of Czechoslovakia (1968)

On 20–21 August 1968, the Czechoslovak Socialist Republic was jointly invaded by four Warsaw Pact countries: the Soviet Union, the Polish People’s Republic, the People’s Republic of Bulgaria and the Hungarian People’s Republic. The invasion stopped Alexander Dubček’s Prague Spring liberalisation reforms and strengthened the authoritarian wing of the Communist Party of Czechoslovakia (KSČ).

Breastfeeding

Health organizations, including the WHO, recommend breastfeeding exclusively for six months. This means that no other foods or drinks, other than vitamin D, are typically given. WHO recommends exclusive breastfeeding for the first 6 months of life, followed by continued breastfeeding with appropriate complementary foods for up to 2 years and beyond.

Palmar grasp reflex

Palmar grasp reflex (or grasp reflex) is a primitive and involuntary reflex found in infants of humans and most primates. When an object, such as an adult finger, is placed in an infant’s palm, the infant’s fingers reflexively grasp the object.
