Okay. I'm confused is there a difference between newborn clothes and 0-3 months size. If so how long does the newborn size typically last? I'm starting to fear iv wasted a lot of money lol. I have 17 (onesies and sleepers etc ) newborn pieces. And some 0-3 months. I thought they were roughly the same 😳 and any other clothing tips I should know about would be appreciated lol
