How young parents can stimulate their child?

Brain is a neural network and neuro activity is highly active during the early years of the child, as the brain process every input from the environment. The signals flows and get processed through the core of the brain. The network structures and links gets reinforced based on the stimulation experienced by the child. Parents engage though different activities, daily routines need to be set and parents need to engage positively with the child. 

It is not necessary to buy special products and services for the routine activities. Earlier joint family setup was very conducive for the child as we have numerous relatives all engaging with the child simultaneously, with the growing nuclear family setup the number of interactions reduce. Some of the common everyday activities are

• Love and affection which come pretty naturally need to be expressed to our children, the unconditional love allows for the creation of strong self-confidence and reinforces bonding between the family.
• Talk and sing in the mother tongue. Continue to describe the activity that you are doing, sing as a song and enjoy the moments with the child. The descriptions provide language nutrition that helps in developing vocabulary in children and also helps connect with the environment.
• Respond to the queries from the child.in a right manner. Never ignore any question from the child, your response provides confidence, sense of trust and emotional connect.
• Touch the infant through cuddling, feeding and also build eye contact.
