I've read an article entitled “How to raise a healthy child”. The article suggests to plan the pregnancy in advance and claims that a woman should try to have a child between 25 and 32 years old. Two years are often needed to start a pregnancy and many couples have fewer chances to start a family due to infertility problems. The article says that the likelihood for a woman to have a child after 35 years old decreases by 10% each year and thus that women should have had their first child before. Moreover, women mustn’t have a baby at 40. This makes me feel nervous as l don’t want to have a baby for now. The article also told that a mom shouldn’t be underweighted because she runs the risk of giving birth to a premature or underweighted baby. Being underweighted for a woman can also reduce her chances to get pregnant as well.

I read an article entitled, “How to Raise a Healthy Child”. [In the title of an article, we typically capitalize the first letter of all the head words. I did this for example. In a real case, you should use exactly the title the author gave the article.] The article suggests planning the pregnancy in advance, around 25 to 32 years old. Two years are often needed to start a pregnancy, and many couples (have a lesser chance/are less likely) to get pregnant due to infertility problems. The article says that after 35 years of age, the possibility of getting pregnant decreases by 10% a year, and at that age the child should be already delivered. [<-- In the last clause of this sentence, I think you mean that the entire pregnancy, plus final delivery, should ideally be completed prior to age 35. Is that correct? The meaning was not 100% clear to me.] Women mustn’t have a baby at 40. This makes me feel nervous as l don’t want a baby now. The article also says that a mom shouldn’t be underweight [Do you mean underweight? I think you must mean that.] because the baby can be born prematurely or the baby may be underweight. Being underweight can decrease the possibility of getting pregnant as well.
