Intelligent development test (4 months)
The evaluation method of classified items can make the baby turn over on his back (from supine to prone) through standard big movements, and can help the baby sit on an adult's lap with toys from supine to lateral lying, and hold his hips under his waist with both hands, and can sit on his own for more than 5 seconds with the help of adults. Fine movements can take the initiative to hug the table at a distance of 2.5 cm from the hand. Put toys such as rattles on the desktop 2.5 cm away from the hand, reach for the toys 2.5 cm away from the hand on the desktop actively, hold the cognitive head tightly, and turn to the sound source to sit. When the rattle is away from the baby's ear 15 cm, you can turn your head to find the sound source and laugh loudly to attract the baby, such as tickling and holding it outdoors. Arouse happy emotions, laugh loudly and talk alone. When the baby is quiet, observe its pronunciation. There is no point in talking to yourself. Emotion and excitement at the sight of food (mother's breasts) Observe the baby's expression when he sees his mother's breasts or bottle. When you see food, you stare at it and feel excited. When I saw my mother's reaction, I reached out and asked to recognize strangers (staring at strangers, avoiding, crying, etc.). ).
