According to figures released by the Office for National Statistics (ONS)，the U．K．has about 7．7 million families with dependent children，of which 3．7 million have just one child，compared to 3 million with two and 1．1 million with three children or more．The number of families today with just one dependent child is now 47 percent and will likely rise to more than 50 percent in a decade．As the ONS confirms，“It appears that families are getting smaller．”
One obvious reason for this could be that women are putting off having children until they have established careers when they are bound to be less fertile．But it could just as well be a matter of choice．Parents must consider the rising cost of living，combined with economic uncertainty and an increasingly difficult job market．And this trend may continue growing as having an only child becomes more normal，which seems to be the mood on the mothers’ online forum Mumsnet，where one member announced that she “just wanted to start a positive thread about how fab it is to have an only child”．
She had received 231 replies，overwhelmingly in the same upbeat spirit．Parents of only children insist there are plenty of benefits．Nicola Kelly，a writer and lecturer who grew up as an only child and is now a married mother of one，says her 15  year old son seems more grown up in many ways than his contemporaries．
Not all products of single      child families are as keen to repeat the experience．In a moving recent account journalist Janice Turner wrote about her own keenness to “squeeze out two sons just 22 months apart”as a reaction to her only child upbringing．
She was placed on a pedestal by her doting parents，whom she punished with a “brattish，wilful” rejection of everything they stood for．Desperate for a close friend she was repeatedly shattered by rejection and refers to her childhood as being “misery”．
Writer and clinician Dr．Dorothy Rowe，a member of the British Psychological Society，says that we all interpret events in our own individual way and there are some children who no matter what their circumstances feel slighted，while other children see the advantages of their situation．
However，the one part of life that is unlikely to get any easier for only children is when they grow up and find themselves looking after their own parents as they become older．
