• Every day, play and cuddle with infants.
• Babies are not forced to cuddle or rushed to respond to every scream.
• You should engage in daily speech with infants through your native language.

• Keep children away from using digital media.

B. 4-6 months baby:

• Newborns need their parents to copy their sounds and receive positive feedback when they reflect back sounds.
• Making interesting items accessible to infants, placed on the floor within their reach, lets them explore more easily.
• Introducing children to different parts of the world requires taking them into outdoor environments.
• Sucking on fingers tends to relax kids. The condition is harmless. Don’t give up on it too early.

C. 7 – 9 months baby:

• Allow your child to safely explore by dropping, banging, and tossing objects, as these activities help to develop coordination and curiosity. If your child becomes noisy or overly excited, respond calmly with gentle guidance and positive interaction rather than punishment.
• Provide children with safe household items and toys that encourage play, exploration, and learning while ensuring there are no risks of injury or choking.
• Peek-a-boo is an excellent activity to be done with the infants as a bonding activity. Children should have a box or cloth placed over their most cherished toys.

D. 9 – 12 months baby:

• Demonstrate simple daily activities and skills so children can observe, learn, and gradually try them independently. If your child creates a mess while learning, stay calm and gently encourage cleaning and organizing as part of the learning process.
• Making a regular sleep-wake schedule for children is important.
• Provide children with books, paper, crayons, chalk, and other safe writing materials to encourage scribbling, creativity, and early learning skills. A child’s healthy development grows best through love, patience, consistent care, and supportive parenting.
