If that kitchen was a twenty-year-old one, then it was awfully pristine. The BBC Props department are usually better than that.
Oh - another thing I noticed: Amelia made dolls of the "Raggedy Doctor"* and played with them. A child growing up in the mid-nineties would have had a TV, a Nintendo, etc. Playing with home-made puppets is the sort of thing that a kid in the late-seventies/mid eighties would have done.
And the garden: didn't it have vegetable plots and such? Very fashionable now, very normal in the seventies/eighties, but I don't think I know anyone who had one in the 1990s. Of course, I spent the 1990s in suburbia, so that may be a narrow sample size.
I hadn't realised the incongrueties until now due to the fact that her
childhood seemed to be very similar to mine (born in 1979)!
*Co-incidentally, Raggedy Anne was a very popular TV show in the
late seventies...
