In comparison with the past, nowadays many couples decide to have 'much less' (nie pisz tak, to jest dziwactwo, jest slowo 'fewer' i tutaj ono pasuje) children. There is a very popular family model "2+1" which means two parents and 'one children' (popatrz na to. Cos tu nie tak?), particularly in (ja dalbym przedimek) developed countries. (tutaj cos brakuje - skaczesz z jednej mysli do drugiej) It is positive for the child to have many siblings?
First of all, it is generally agreed that in homes where 'there is' (od kiedy mieszmy l. mnoga z l. poj?) many children there are stronger relationships 'betwen' (ortog) them.
On the other hand, living in (przedimek) home where there are so many people could be troublesome sometimes.
What is more, having many children means much more expenses for their parents and consequently, sometimes children from 'the' (niepotr) large families cannot have things which they want to have.
To sum up, there are many advantages and disadvantages of living in 'the' (nieppotr) large families and 'it is sure' (bardzo dziwne okreslenie- zmien) that opinions about it are differentiated.
