walking is rickets.

_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.
