When a mom and dad have a baby, they have to take care of that baby and make sure it has everything it needs. This costs money and is called the "cost of raising a child."
There are lots of things that go into the cost of raising a child, like food, clothes, and toys. The baby needs to eat, so its parents have to buy bottles or breast milk and baby food. The baby grows really fast and will need new clothes a lot, which can also be expensive. Toys are also important for the baby to play with and learn from.
Sometimes, the baby gets sick and needs to go to the doctor. This is also expensive because the doctor will charge money to help the baby feel better. The baby will also need medicine and maybe even surgery if it's really sick.
The baby will also need a place to sleep, like a crib or bassinet. The parents will have to buy diapers and wipes to keep the baby clean and healthy.
As the baby gets older and goes to school, there will be even more costs, like books, pencils, and clothes for school. The older the child gets, the more expensive it becomes to raise them because they have more needs and wants.
Overall, raising a child is an expensive but very rewarding thing to do. Parents have to work hard and make sure they have enough money to take care of their baby, but they also get to watch their child grow and learn new things every day.
