All kids are different. And they differ from their very birth. Someone big, someone small. Someone sleeps all day and night, and someone cries all day and night. And parents have to find an approach to their child.
Of course, it's easy when the baby sniffs quietly in his crib all day. But what if the baby is in the arms of adults for days, demanding constant attention? After all, in addition to classes with the baby, mom needs to have time to cook dinner, and wash, and iron!
Most often, babies are capricious, in which inexhaustible energy is laid by nature. The child is bored just lying, but he does not want to sleep - after all, he is not tired yet. In this case, parents need to allow the baby to be active - to massage him, show various pictures, books, talk to him, read poetry. All this will certainly tire the baby and he will soon want to sleep.
Do not worry that something is wrong with the baby if he requires more attention to himself than other children. He's just more attached to his mother and more curious and active. This is even good, most often such kids develop faster and learn everything new with redoubled interest. But it is worth being able to distinguish when the baby is just naughty, and when he complains about something, for example, pain. And it's easy to do. A naughty baby can easily be distracted from his tears if he is interested, for example, with a book or a toy. With a child who is in pain, this will not go away.
There is one point. You should not run headlong to the baby at his first tears. Otherwise, the baby will behave this way for a long time: not enough attention - crying, wanting something - crying. You need to tell the kid that he is doing the wrong thing, you need to teach him to ask for something without tears, for example, pointing with his finger with the word "give." And you also need to accustom him to independence - you should not approach the child if he sits quietly himself, without parental involvement. Sometimes you yourself need to leave him alone in the room, occupying himself with toys.
In short, you need to act according to the circumstances. The main thing is not to despair that such a whiny baby has appeared in this family. With age, this will pass, but the main task of the parents is to grow him as independent, smart and healthy as possible.
