If your child just learned to walk, then this is normal. It will take some time for your child to perfect walking on his own and also avoid falling down. Encourage him to walk more. Do not shout or make him feel bad. Take him out so that he can walk outside. Make him play with other children his age, which will encourage him to walk and be more like the children around him.

At three years children weigh between 12 - 15 kgs.

You need to start talking with her yourself. You should also read stories to her daily. Take a book, point at the words and read them to her loudly and slowly. Try to speak only one language with her. Ask her questions, where she can give simple answers. This is the best way to encourage your child to speak more. Most of the children learn most of their words in the second year.

We should keep on telling them. They'll surely follow. We should show the examples too. We think that children can't understand. But they can very well understand. They r very much connected to our mind and heart. But as they grow their mind diverts in various other activities. Girl child can easily understand well if u say politely.
But we need to tell the reason for the sorry and thank you. It will be a satisfaction for them.
They learn from parents. So, parents are also a main source in learning the manners. If u keep on shouting they feel as if they also should shout and yell to make their work done. *kids see and learn everything from their parents*
