I loved looking for clothes for the children up to 18-24 months. After this, instead of the nice pastels, flowers, bears etc it becomes tracksuit bottoms for boys with slogans or garish patterns. It all looks cheap and nasty. Even a lot of the Next stuff is particularly bad for little boys.
I love the Boden/ Frugi / Blade & Rose stuff but most of that is not an affordable day to day option with 3 under 3 ( Vinted and sale shopping aside).
I like my children to be nicely dressed, not in awful tracksuit type outfits. I don't understand why at least up to 5 they don't have more of the baby / toddler designs. More pretty pinafore and soft colours for girls and dungarees, bears, blues, browns and burnt oranges for boys etc.
