Where are these adorable clothes from?!

Hey ladies! Hubby & I have been blessed with a "dilemma"... Through family/friends at the baby shower & coworkers at work, we have gotten a TON of 0-3 month size clothes, including multiple duplicates, & not many larger sizes. We are so thankful & blessed!! But... We want the gifts to actually be used... Is there anyway to determine where some of them are from without asking the gift giver? We want to exchange some for larger sizes so the gifts will be put to use, but I don't know where to start!! Someone helpppp! 😘
