Does anyone know if the boden sizing for babies runs large or small? DD is 7 months, but still wearing 3-6 month clothes from M&S for example. Seen some lovely boden appliqué pinafores but not sure whether to get them in her current size or the 6-12 month size. (If it helps, she's not quite 15lb and I think roughly 68cm tall). I don't mind waiting a couple of months for her to grow into them, but don't want to be waiting 6 months or something crazy (I'm too impatient!)
