Hi all! I was looking for this thread...
My children are 9, 11 and 13. The bits we've kept from my French upbringing are these:
Always eating together. I echo what others have said re veg, etc. My children have always eaten what we eat. No excessive fussiness, no weight problems, no complaints.
French bedtimes. Our children have never gone to bed earlier than 8pm. They would have been up at 6 if we'd opted for any earlier, and it just wasn't worth it.
Now that my two oldest are approaching teenagey years, I still expect them to behave like human beings. I have no intention of pandering to any kind of moronic teenaged behaviour that holds the whole family to ransom (am thinking of certain of my son's 13 year old friends), nor allow any rudeness.
Growing stuff and knowing where your food comes from.
Snacking (aaaargh!). Nope. Except when they get hope from school, and have gouter before starting homework.
No telly before homework finished.
Expect them to help out around the house. They do two days a week each as parents helpmeet. If they moan, I tell them could be a French baker's child and have to work in the shop from 7am all weekend, or a farmer's child and have to help out every hour they are not in school. That usually shuts them up.
Barbapapa, Sorcière Camomille, Astérix, Tintin. Obviously.
politeness towards other people
What I keep from my English background:
extended breastfeeding (up to 24 months with my youngest)
staying at home with them while they still need me (not that the UK is set up for easy access to the opposite scenario anyway...)
weaning when they were ready, not according to schedule
encouraging them to question everything in an open, philosophical way. Accepting that there may be many ways to do the same thing.
There are probably many more, but I have to go and walk the dog right now...
