The form of babble becomes various, and babies show the sensitive response against the high and low of a voice and a tone color. Sometimes they laugh with a loud voice.
They can keep their neck steady and turn their body. In case of the fast-growing babies, they start crawling from 5 month old. From this time they look around the environment positively and their curiosity is getting more.
At this time the basic of a cranial nerve is set and the brain grow well. So please give an impulse to the five senses as the interested and various toys.
And they like to approach whatever they hold to their mouths so the toys must be confirmed whether the material is non-poison and safe or not. |
