EDMONTON -- More Canadians, it seems, are changing dirty diapers, serving up spoonfuls of mushy peas and getting tongue-tied over Dr. Seuss books before bed, if the latest census figures from Statistics Canada are any indication.
The number of children in Canada aged four and under jumped 11 per cent between 2006 and 2011 the highest rate of growth for that age group since the five years between 1956 and 1961, the trailing edge of the baby boom, census numbers released Tuesday show.
And though the increase pales in comparison with the dramatic spike in births that followed the end of the Second World War, Canada's baby bump is definitely showing: it's the first time in 50 years that Statistics Canada has recorded an increase for that age group in every province and territory.
"I love being a mom,'' said Erin Koestlmaier, a mother of three in Edmonton. "Even when I was a little girl, I loved kids and babysitting and I always knew I was going to be a mom.''
The 33-year-old runs her own business called Fit Mommy, teaching "strollercize'' working out while pushing a stroller and boot-camp workouts to women who want to lose their baby weight or generally keep in shape.
To keep up with more mommy demand, she'll soon be adding another class to her schedule.
Koestlmaier said her clients are mostly first-time moms, although some have several children. She's currently negotiating with her husband, Mike, about the size of her own family.
"He's not necessarily on board, but I'd like to go for a fourth,'' she said with a laugh.
Previously released population statistics show more people in Canada are having children. The national birth rate increased slightly from 1.59 in 2006 to 1.67 in 2009. In Alberta, the rate is among the highest of the provinces; it was 1.8 in 2010.
Not surprisingly, the latest increase was felt most profoundly in the Prairies, which have become magnets for job-seeking, working-age families looking for a place to put down roots. In Alberta, the growth rate among kids four and under was 20.9 per cent, followed by Saskatchewan at 19.6 per cent.
Quebec also posted a strong increase at 17.5 per cent, as did Nunavut at 15.7 per cent.

Another reason for Canada's baby bump may simply be that there are more moms. Statistics Canada attributed the spike to modestly higher fertility rates in most regions, as well as a growing number of women aged 20 to 34 traditional child-rearing years.
"This is the main reason for the increase,'' said David Foot, an economics professor at the University of Toronto and co-author of the 1996 bestseller, "Boom, Bust and Echo,'' which explored how demographics can explain economic trends.
The spike in small children is the result of the children of baby boomers the so-called "echo'' having kids of their own, Foot said.
"These echo boomers, now in their early 30s, are starting their own families,'' he said. "These are the boomers' grandchildren being born.''
Roderic Beaujot, a demographer at Western University's Centre of Population, Aging and Health in London, Ont., said while "pure demographics'' is behind the increase, other factors could be in play as well.

For years, women have been choosing to have children later in life, spending more time in school, starting careers and establishing personal relationships. Now, they're starting families.
"In some sense, the delay is coming to an end,'' Beaujot said. "Because you can't delay much more.''
Beaujot also said he suspects more working women are choosing to have children. The fertility rate went into a nosedive after the baby boom, and experts attributed the decline to more women joining the workforce.
"Women were doing more paid work, so they didn't have time to have children,'' Beaujot said. "Having children has become more positive.''
Provinces with more working women now tend to have higher fertility rates, he added. Women are feeling more confident about the decision to have kids, in part because there are more government policies to support families, such as parental leave.
Quebec in particular has a landmark $7-a-day daycare program. And the federal government gives families $100 for every Canadian child under six as part of its Universal Child Care Benefit.
"I just take the money I get from Stephen Harper every month and pop it into their RESPs,'' said Karen Hach, a mother of four young boys in St. Albert, a bedroom community north of Edmonton.
Hach and her husband Mike began planning for their children's education as soon as they were born, she said. After all, the cost of sending four kids to university adds up quickly.
"God I hope they don't all want to be doctors,'' she said.

Despite her husband's stable, well-paid oilfield job, Hach said the family still watches its cash flow carefully. Even with her oldest son in school, putting the other three in daycare would be too costly, so she's staying home with the kids for the next little while.
The Alberta government has helped create 20,000 new daycare spaces in recent years to keep up with demand both from the province's high birth rate and the families who have been flocking to the province.
The spaces include after-school spots for older children, because many mothers who do stay home eventually go back to work, said Cathy Ducharme of Alberta Human Services.
A strong economy, especially in Alberta, is also helping fuel young families, Beaujot said.
"Young people feel confidence in the labour market. They can even withdraw from the labour market for a while, knowing that they could get a job when they go back in ... It gives them confidence so they can have children, and it's not particularly risky from an economic point of view.''
Hach said most people in her neighbourhood have children. Five couples on her cul-de-sac have kids four of them have three or more little ones.
People seem to be placing more importance in their lives on having children these days, she said.
"It seems to me more people are concerned with family. It's nice when kids have other kids around.''
Highlights from the 2011 census:
The number of seniors aged 65 and over in Canada increased 14.1 per cent to nearly five million, a faster rate of growth than that for children aged 14 and under (0.5 per cent) and people aged 15 to 64 (5.7 per cent).
Seniors accounted for a record high of 14.8 per cent of the Canadian population in 2011, up from 13.7 per cent five years earlier.
The number of children aged 4 and under increased 11 per cent, the highest growth rate for that age group since the latter half of the baby boom between 1956 and 1961. It marks the first time in 50 years that Canada has seen an increase in small children in every province and territory.
Seven of the 10 municipalities with the highest proportion of seniors were in British Columbia.
In 2011, the proportion of seniors was the highest in the Atlantic provinces, Quebec and British Columbia.
For the first time, there were more people in Canada aged 55 to 64 -- typically the age group where people leave the labour force -- than aged 15 to 24, when they typically enter it.
In 2011, people aged 15 to 64 -- the working-age population -- represented 68.5 per cent of the Canadian population, the highest proportion of all G8 countries except Russia.
People aged 100 or older comprised the second fastest-growing age group in Canada, after those aged 60-64; there were 5,825 centenarians in 2011, an increase of 25.7 per cent since 2006.
Nearly one in five people were aged 65 and over in Peterborough, Ont. (Shown here), and Trois-Rivieres, Que.; in Calgary, the ratio was less than one in 10.
Among smaller communities, the Vancouver Island community of Parksville, B.C. (shown here) and Elliot Lake, Ont., had the highest proportion of seniors -- 38.6 per cent and 35.1 per cent, respectively, more than twice the national average of 14.8 per cent.
