In India we have grown listening to the story of Abhimanyu who was the son of Arjuna and Subhadra. The legend goes that Abhimanyu's battle training and education started in the womb only. He learnt all the battle secrets from his father while being inside the womb as he overheard the narration to his mother by father. This makes me a staunch believer of the fact that a baby can listen to you while in the womb. So I started to teach my child to be compassionate and humble from the time I conceived. Try it. Talk to your baby inside your womb about your thoughts, about your feelings, about everything. I bet he or she is going to respond.

I bet you speak to your baby in your womb about the developments happening around he would surely respond to you. Get ready for some kicks in your belly when you share a gesture of your good doings. And getting acknowledgement from your baby is going to add to your happiness manifold.
Secondly, do not leave an opportunity to shower your love and care on your baby or toddlers. These kids are sensitive form an age of about 4 months onward. At-least I could sense that in my baby. Check it out when you simply raise your voice your child might get hyper and start to cry. I observed this in many babies. My neighbor's daughter is just 5 months and when we all meet and suddenly our decibel levels go high because of anything, it might be a shrill voice or a loud call to save something from falling, the baby ends up crying inconsolably.
And as the child grows you can observe your child imitating you completely. I observed this in my son. My husband had got a small little bruise on his leg. The moment my son saw the bruise he started to talk sweet with his father and care for him. We all felt happy for his cute talks. But heart of heart I was happy because I could see my child being caring towards other's feelings and sentiments.
Thirdly, Praise thy efforts. Everyone is waiting to be praised for one's good deeds. I feel delighted by my husband's compliments for good food cooked, my husband feels proud of all the praises for his presentation. So you can imagine how elated your child would be when his effort to be a caring individual is accolade. He would start to associate the reward to the act.
1. Start at home. The way you speak to your help and all those people who are from a humble background the same way your child is going to react as soon as he sees a person of that status. I have always tried to explain it to my child that God created everyone equal so everyone should be treated at par.
2. Indulge in some charity every two months. Every two months because kids have a shorter memory span. So keep the charity fresh. This way he would get used to the idea of taking care of things as things like his toys are to be given ahead to needy kids.
3. Involve your kid in selecting flowers or card for your unwell friend or relative. In case you involve your kid to select the color of the card then he would make it a point to deliver the same to your friend and with all his heart into it.
Last but not least it is very important to help your child differentiate between compassion and benevolence. Being a caring individual should be his inherent quality that walks with him always and in every situation.
