Many parents may be having a baby for the first time, so they don’t know much about some basic situations. So let me introduce the specific development standards of April babies. Let me give you a detailed introduction. I hope it will be helpful to everyone. This is what I would like to see most.

1. Developmental standards for four-month-old babies - body and appearance

By the end of the 4th month, the posterior fontanelle will have closed; the head will still look large because it grows faster than the rest of the body, which is perfectly normal; his body will soon catch up.

3. Development standards for four-month-old babies - physical skill development

A four-month-old baby can hold on to his clothes and quilt; shake and stare at the rattle in his hand; hand-eye coordination begins to occur; and when lying flat, he will look up and see his little feet. When lying on your stomach, you will straighten your legs and slightly lift your buttocks. Can't sit independently yet. He is interested in all the objects around the crib and wants to grab and touch them.

4. Developmental standards for four-month-old babies - language development

At four months, babies will slowly start to talk with a smile and make vowel sounds like "ah, oh, oh". The better the baby's mood, the more sounds he makes. Mom and dad should talk to their baby when the baby is in a high mood, send more voice messages to the baby, and give the baby more opportunities to practice pronunciation. Let your baby go outdoors more often, listen to the birds singing, the sound of flowing water, the sound of wind blowing through the leaves, and keep telling your baby where these sounds come from. Make vowel pronunciation shapes for your baby and let him imitate mom and dad in speaking. The development of infant language follows certain rules. The initial stage is the language perception stage. Babies first perceive sounds by listening and seeing, and gradually distinguish speech, and finally develop to making speech themselves.

5. Developmental standards for four-month-old babies - visual development

At this point he may be able to track any object moving within the semicircular field of vision in front of him; eye coordination can also allow him to deepen his field of vision when tracking objects approaching and moving away from him. His vision is flexible and can shift from one object to another; his head-eye coordination is good, and his eyes can move 180 degrees from one side to the other following the moving object, and he can track objects. For example, if a small ball slips from his hand and falls to the ground, he will use his eyes to find it.

6. Developmental standards for four-month-old babies - cognitive status
