It is well worth looking through any clothes you have bought or were gifted and holding them up for size. Sometimes, the sizing isn’t quite what you might think they are from the label. Use the size on the labels as a guide, not a rule book. There will be that one outfit that is labelled at 3 months that will still fit your baby at 9 months, just like the 12 month size labelled item that your baby will have grown out of by 9 months.
