Child Development and Early Learning

Building the capacity of communities potentially exposed to hazards to resist, adapt and recover. ZeroHunger Heroes Set up a monthly donation today to ensure that hungry people get the nutritious food they need month-after-month, no matter what. To realize the full potential of our globalized economy, national governments must expand social protection schemes for the most vulnerable.

Providing this opportunity for equitable economic growth will raise the purchasing power of the poorest 2 billion people which in turn will create incremental demand, generating new jobs and jump-starting local economies. Pave the road from farm to market. We must innovate and invest in making our supply chains more efficient by developing sustainable durable markets.

To support these markets, we must also improve rural infrastructure, particularly roads, storage and electrification, ensuring farmers ability to reach a wider consumer base. In developed countries food is often wasted on the plate, while in developing countries it is lost during production, as crops go unused or unprocessed because of poor storage or because the farmers cannot get their goods to market. Encourage a sustainable variety of crops.

Today across the globe, four crops rice, wheat, corn and soy represent 60 percent of all calories consumed. Addressing the challenges of climate change, and food availability and food access will require helping farmers explore and identify a more diverse range of crops.

To achieve this, we must work with farmers ensure they have access to the necessary tools and skills, and build a market by educating communities about the nutritional importance of eating a wide range of foods.

Nothing is more important to the development of a child than good health and nutrition, particularly in the first days from conception through to the age of two. To prevent stunting and to promote healthy development, we must ensure that children and nursing mothers have access to the required nutritious foods.

The Global Goals 17 goals to end extreme poverty, inequality and climate change by World Breastfeeding Week, celebrated this year from August, is an annual event highlighting the critical importance of breastfeeding for children across the globe. Breastfeeding gives children the healthiest start in life and is one of the simplest, smartest and most cost-effective ways we have of ensuring that all children survive and thrive.

There are approximately million women workers in the world. Many of them return to work soon after delivering babies, and they need supportive national polices and legislation — such as paid maternity leave and breastfeeding breaks — to enable them to continue breastfeeding. There are also millions more women working in the informal, seasonal or part-time economy who face even greater barriers to breastfeeding.

They need strong family and community support to manage the demands of work and breastfeeding their babies. Providing this support is the right thing to do for both babies and mothers: It also makes good economic sense. Women who have adequate maternity benefits value their employers, leading to increased productivity, job satisfaction and loyalty. UNICEF is working to support national governments in making the world a friendlier place for all mothers who wish to breastfeed.

Impact on child survival and global situation In the last two decades, child mortality has decreased considerably, but close to 7 million children under five years of age still die each year, mainly from preventable causes. Of those, newborn deaths now represent nearly half of all child deaths under five years. Early and exclusive breastfeeding helps children survive, but it also supports healthy brain development, improves cognitive performance and is associated with better educational achievement at age 5.

Breastfeeding is the foundation of good nutrition and protects children against disease. In this way, breastfeeding allows all children to thrive and develop to their full potential. Optimal breastfeeding of infants under two years of age has the greatest potential impact on child survival of all preventive interventions, with the potential to prevent over , deaths 13 per cent of all deaths in children under five in the developing world Lancet Breastfed children have at least six times greater chance of survival in the early months than non-breastfed children.

An exclusively breastfed child is 14 times less likely to die in the first six months than a non-breastfed child, and breastfeeding drastically reduces deaths from acute respiratory infection and diarrhoea, two major child killers Lancet The potential impact of optimal breastfeeding practices is especially important in developing country situations with a high burden of disease and low access to clean water and sanitation.

While breastfeeding rates are no longer declining at the global level, with many countries experiencing significant increases in the last decade, only 39 per cent of children less than six months of age in the developing world are exclusively breastfed and just 58 per cent of month olds benefit from the practice of continued breastfeeding. A growing number of countries are demonstrating that significant and rapid progress is possible, with 25 countries showing increases of 20 percentage points or more.

Breastfeeding is for every creature in this animated short from China. Benefits of breastfeeding Breastfeeding has an extraordinary range of benefits. Breast milk provides all of the nutrients, vitamins and minerals an infant needs for growth for the first six months, and no other liquids or food are needed.

In addition, breast milk carries antibodies from the mother that help combat disease. The act of breastfeeding itself stimulates proper growth of the mouth and jaw, and secretion of hormones for digestion and satiety. Breastfeeding creates a special bond between mother and baby and the interaction between the mother and child during breastfeeding has positive repercussions for life, in terms of stimulation, behaviour, speech, sense of wellbeing and security and how the child relates to other people.

Breastfeeding also lowers the risk of chronic conditions later in life, such as obesity, high cholesterol, high blood pressure, diabetes, childhood asthma and childhood leukaemias. Studies have shown that breastfed infants do better on intelligence and behaviour tests into adulthood than formula-fed babies. Virtually every mother can breastfeed , if given appropriate support, advice and encouragement, as well as practical assistance to resolve any problems. Studies have shown that early skin to skin contact between mothers and babies, frequent and unrestricted breast feeding to ensure continued production of milk and help with positioning and attaching the baby increase the chances of breast feeding being successful.

Breastfeeding also contributes to maternal health immediately after the delivery because it helps reduce the risk of post-partum haemorrhage.
