Almost all families at present are small - not as the same as in the past, when families were larger

Advantages and disadvantages with a small family

Almost families at present are small family, not the same in the past cause family are larger. Small family in the modern world have some advantages and disadvantages.

I think here are two main benefits when living in a small family. That is when parents have less children, they will pay more attention for their children and sons get good condition about education, health, ect. Next, in the small families, parents have more time so they earn more than big families. As a result, their life are more comfortable as well.

Beside, I believe there are three disadvantage. Firstly, children, who live in a small family, learned less social skills because there are few people in the house around them.Cause many helps and protections from their mother and father, they can't help in the house and depend themselves. Consequence they become irresponsible and selfish, that is second disadvantage. Lastly, they have few brother, sitter and both mother and father must earn, so they usually feel alone.

In my opinion, the disadvantages of the small family were worse than advantage. If parents don't teach them carefully about how make good behavior and a right lifestyle, they will be irresponsible.

Hello

Your text is understandable, but some of the sentences sound little awkward. Check the applied corrections below:

Almost families [...] Nowadays, most people prefer to create small families - contrary to what it used to be the case in the past.
Small family [...] There are both: advantages and disadvantages to such a way of acting.
I think [...] There are two main benefits to having a small family.
and sons get good condition about education, health, ect. [...] you should consider removing this part of the sentence... it's redundant and poorly constructed.
Next , [...] Also, parents in small families are more likely to be well-off, because they have more time on their hands to earn money.
Beside [ ...] There are, however, some disadvantages to the concerned family-creating strategy, as well.

You should be able to take care of the rest of the text on your own. Consider reading some articles in English written by native speakers - you need to get a better 'feel' of the language.

I hope this will help. Regards.
