It sounds like many of you would enjoy "Our babies, ourselves: How Biology and Culture shape the way we parent" by American anthropologist Meredith Small.
I am a Brit married to an American. Our three kids were all born in the US and we are now in Germany.
USA
Local hospital has been certified "Baby friendly" by the UN (or somebody) this meant tons of very supportive and encouraging parenting classes offered before the birth about birth/becoming a parent where mothers and fathers were shown how breastfeeding works and how to support mum and baby.
Labor and birth in the same room with rooming in with baby and a bed for dad/partner.
Lactation specialist to help you before you left hospital.
Breast feeding Unit in the hospital that you could call or visit any time with bambino with questions/concerns about BF. Also hospital shop selling/renting breast pumps, slings etc. etc.
I cloth-diapered first DD and kind of fell off the wagon with second. With both I had a cloth diaper service that dropped off a huge bag of clean cotton diapers every week and took the festering bag of dirty ones away.
My very loud second dd was frequently complimented on her "great voice" by admiring Yanks i.e. you could hear her two rooms away.
Shy children were thought to be suffering a terrible malady that literally needed intervention by child-psychologists at a young age. Parents of shy children were very worried and apologized for their child's social bashfulness as a personality defect. I am talking 5 year olds.
Bragging (boasting) about your children/grandchildren was totally socially acceptable and encouraged by the selling of "Brag Books" small photo albums you carried everywhere to show random strangers on the bus or at the supermarket (maybe outdated by FB etc. now).
Sports mad culture and children started in "pee-wee" soccer/football/baseball/basketball from pre-school years.
Children catered for wherever you went: child hairdressers, party stores, playgrounds, children's menus etc. etc. Every restaurant/store had high-chairs, changing facilities etc. Everyone very welcoming of children, the children were talked to directly and asked about their preferences etc. Any "mean" or overly strict/harsh coach or teacher immediately sacked after complaints from parents.
Many families with three or more kids.
Male Americans wear the same uniform from the age of 2-92. Long shorts past the knee, t-shirt, baseball cap and sneakers.
A lot of anxiety around education and whether your child will "make it" and be a success in a highly competive view of life where there are "winners" and "losers". (I see the same heightened anxiety transferring to the UK)
Germany
Immediately my American children that were considered "so polite" in the US for saying "please" and "thank you" were considered rampaging barbarians in Germany.
Loud children are severely frowned upon here, even being noisy in the park or swimming is a social no-no.
Suddenly my über exuberant 2nd DD was being frequently corrected for being too loud.
Organization is considered to be an innate quality. Children MUST be organized from the moment they enter school (at 6). Teachers hyperventilate if your child forgets the correct book for class.
Children wear huge, expensive, specially designed school backpacks and schlep all their gear and books in and out of school everyday as they have no lockers or anywhere to leave their belongings.
Children from 5 and up take themselves off to Kindergarten or school in the pitch black of winter (possible snow and/or hail) If you walk them to school each day you are not letting your child learn to be independent.
Of course they start school at 7:45 and finish as early as 11:45 to walk back home to eat the hearty midday meal lovingly prepared by Mutti.
Our youngest was 2 when we arrived and I was soon to discover the wonderful world of German tights for boys, helpfully color coordinated in navy, grey or bottle green. Also all children wear hats, gloves and scarves with no complaints. My two year old son found this all way too frustrating and frequently discarded various items of winter clothing before we had reached the bakery across the road. There he outed me as not just a Bad Mother but a foreign one by stripping his coat and sweater off and revealing he was wearing a short-sleeve t-shirt in January. Absolute scandal and horror reigns as German Omas hoik bosoms in unison.
