1. prism boxes
these prism boxes by olga bielawska are amazing. i want 1 (or 3!) and am inspired to diy, though i doubt they'd turn out as amazing.
danish brand flexa has a really beautiful crib (cot) and convertible (high) chair that i am totally crushing out on. safety regulations and standard crib sizes often hinder amazing brands like this being sold in the US but if i could waive my magical wand....
