I have one daughter and do dress her in a lot of pink, as she has ginger hair and it suits her best. I would like a crossover with pink and blue, to see light pink t-shirts and shirts etc for little boys, if I have a son he'll probably be ginger too and will therefore look fabulous in pale pink.
Mainly shop for her in Gap, Next, and supermarkets (George have some really nice things but the fit is very very wide, I find). I've also had some brilliant charity shop and online boutique finds and she does have some Mini Boden but I doubt she'll get any more as the summer stuff was atrocious quality and got sent straight back.
I would like to see more greens and greys in children's clothes, and a wider variety of reds - there seems to be a lot of bright red but not much plum or maroon. I like white for kids as well, providing the material is good quality and washes well.
There is far too much lilac/that weird sort of dark coral for girls, and fgs STOP MAKING SO MANY BEIGE, NAVY AND BROWN THINGS FOR LITTLE BOYS! Though boys do generally get better prints - I remember M&S doing blue dog-pattern babygros but the pink equivalent didn't have dogs, or cats, or birds, it had "ain't I cute" or similar bollocks. And don't get me started on crowns. Grr!
Kids should wear fun stuff, cool prints and things, they'll spend about 13 years trussed up in a school uniform and then 50 years in "work clothes" so celebrate their cuteness with some fun stuff I say. As long as they are comfortable.
(I do dress my DD in ultimate MN no-nos like jeggings and mini Uggs (present, I wouldn't pay for them) and it's BOLLOCKS to say you don't like them cos they're "uncomfortable", they're amazingly comfy and really practical for crawling/cruising/climbing, just be honest and say you don't like them cos they're a bit "common". She also has some frilly dresses but they are not restrictive and she's allowed to get dirty.)
I despise slogans like "Daddy's princess", "beautiful like Mummy", "Future WAG", "Spoiled and vacuous", "Misogynist in training" etc, (the worst one I saw in Next last summer was "Born to shop" - ARGH) but don't mind some of them, eg "I do all my own stunts" and a child up the road from me has one that says something about sarcasm that always tickles me.
If I had a rich husband I'd open a reasonably priced baby/toddler boutique I think. Or if I had room to sew I'd start making things.
