Croatia here and the only things I know about UK child rearing is from Mumsnet.
Children go to bed much later, but it depends if it is summer or during school year. It is usually very hot during the summer so parents go to a playground at 6 pm and usually return home around 9, even 10 pm.
During school year they usually go to bed earlier. My own, who are 4 and 9, go to bed at 8.30-9.00 pm and wake up a little bit after 7 am.
But our kids nap more, they nap in kindergarten untill they're 5 or 6.
No playgroups in Croatia so parents take even their smallest babies to park when they're 1 month old. People meet there and play with children and considering the fact that most of us live in apartments it is like an extension of our home.
Weaning - all spoon fed.
No kids menus in Croatia, but I would to see them imported. I love them in UK.
I have never heard about somebody who eats at different time then their children and the first time I heard mummy and daddy time was on Mumsnet. To be honest, there are times I would like to live in a country where kids are in bed by 7 pm. Co-sleeping is also often, but we live in small apartments. And because of that kids share till they go to the university.
Not much SAHM mums, but that is because kindergartnes and cheap so even a single mum on minimum wage can afford one easily, at least here in capital where I live. But on the other hand ratio of nursery staff and children is much worse in Croatia.
Children used to play alone outside even from age 5, but that doesn't happen any more. They usually start playing outside with friends when they're 8 or 9.
They start school much later (6 or 7) and usually walk to school from second grade, but it depends how far is the school.
Food - well it depends, but most of the parents cook from scratch (another word that doesn't exist in our language) and children from early age eat what parents eat. Usually one parent cooks and does things around the house, while other parents is in the park.
From what I read on Mumsnet and I do not know is that true, kids are much better behaved in cinema and theatres. I can't remember when I was in cinema or theatre with my kids and heard a noise. They're usually very well behaved.
