Should a child be urged to walk?

Never; he is usually quite willing to do so as soon as his muscles and bones are strong enough.  None of the contrivances for teaching children to walk are to be advised.

When do children begin to talk?

Generally at one year a child can say “papa” and “mamma” or other single words.  At the end of the second year the average child is able to put words together in short sentences.

If at two years the child makes no attempt to speak, what should be suspected?

Either that the child is a deaf-mute or that it is mentally deficient, although this is occasionally seen in children who are only very backward.
