How much clothing should I get in different sizes? FTM.

Ka
Now that I know I'm having a girl 🌸, I got excited and bought a few outfits. But realized I was totally lost as to which sizes I should get. I got a few 3-6 month and one or two 0-3. Should there be a variety? Should I get more newborn? I know they grow quickly so I'm really not sure at all. Thank you for your advice 💕
