I was born in the early 80's. I had long hair and my mum would tie it in bunchies and put me in dresses. I hated both. Once I got to choose my clothes I lived in jeans, t-shirts and jumpers much like my brothers did. Dresses were simply no good for swinging really high on the swings or tearing around on my bike!
I had lots of dolls but I'd also play with Micro Machines, Lego and my dads old construction toys that he kept from the 60's/70's.
This is interesting...old Argos catalogues! retromash.com/argos/
In 1978, mainly primary coloured toys with the exception of a few dolls. In the early 80's lots of primary coloured toys, some pink, and very few children shown playing with them so could make your own mind up about who to buy them for.
Looks like an increase in pink and pastels in the mid-80's with My Little Ponies, Care Bears, JEM, etc all being on the TV. In 1990, more children shown in the images...only girls shown with the play kitchens and ironing boards, only boys with cars.
Baby toys seem to stay primary coloured throughout this time, though in 1999 there's a pink version of the Cozy Coupe car. So maybe the start of pink versions of every baby item but they don't have catalogues past 1999.
