You can give your baby a small toy that can only make sounds. When the toy makes abnormal noise, his eyes and ears will try to find the source of the sound and find out its principle. You can also find some small things with different textures and shapes, let his little hands feel their size, weight and temperature, and let his eyes observe their colors, patterns and sizes. This will allow him to initially establish some basic concepts about the outside world.
Swing a toy in front of him, let him feel and understand the direction and speed of object movement, and encourage him to be good at grasping it. If his hand doesn't respond, you can teach him to grab it with his hand. When he is lying in bed, you can grab his legs and help him walk or ride a bike to cultivate his leg coordination and sports ability. Through these, he will learn the basic essentials of some movements in advance. Of course, you can not stick to one pattern and invent some small games that are not only relaxing and enjoyable, but also beneficial to your baby's intellectual development and action learning. For example:
1, elevator game. You lie on your back in bed, lift the baby up, then put it down, and so on, three or five times at a time. You can also say "let mom kiss you", then put him down and let your faces stick together. He's bound to giggle with joy.
2. Swearing game. When he is interested, you can touch or kiss all parts of his body with your hands and call out the names of all parts, such as hands, legs, feet, mouth and nose, and use these names to impress him.
3. Oscillator game. You hold him in a sitting position and let him sit in front of your thigh. You shake your thighs up and down or left and right with the rhythm of music or your humming, so that he can feel the dynamic movement and the rhythm of music.
