When to start buying?? ๐Ÿ›

I am currently 12 weeks with my 2nd. Had my scan yesterday and baby is perfect. I just purchased a steriliser set as it was half price and now wondering if itโ€™s a bit early? I canโ€™t remember when I started buying for my 1st as I was so paranoid of jinxing the pregnancy.

When did you mummyโ€™s start purchasing?
