My daughter just turned 3 months. She fits in 0-3 still but fits better in 3 months. Do i just buy her 3month clothing or 3-6?? 3-6 looks so big for her right now but she’ll be 4 months in a few weeks this month. Not really understanding these sizes lol.. and for summer she’ll be 6 months in June. I’ve just been buying her 6m clothing. Should i be buying 3-6 for summer or 6-9? But 9mon will be September she won’t be wearing those clothes for sep? But if i get 3-6 what will she have for the rest of the summer once she hits 6 months? Ugh so confused lol help FTM!
