Where can I return clothes from Carters?

Some of them were bought at Macy's but I don't have a receipt for any of them. Will the General Carters store accept the just one you, or precious firsts "sub" brand of carters? Or do I have to go to target? Some were also bought at Walmart. The only two malls near me- one has a Macy's and a target but no carters. One has a carters and a target but no Macy's. One has a Walmart and a carters but no Macy's or target lol. 
So what do you think my best bet is😩😩 They're all from my shower and nobody left any receipts. 🙃 im not sure where they were ALL bought at, some of them just say carters...
