Clothes

Should I go ahead and wash all the baby clothes I have received? Or why did y’all do about washing clothes before baby arrives! FTM here and clueless ready to get her room all clean but trying to figure out which way is best to do this! Thanks in advance, I need all the advice I can get!!

Edit: I know it’s got to be washed before our little girl wears it but I was just wondering if I should wash it all before we see how big she is or just wash a few items at a time! Thanks in advance!
