My baby is 3 weeks old. currently using Huggies XS diapers for her. Lately it's leaving lastic marks which I understand means small size. But it also leaks a lot. Eventhough I change the diaper every 2-3 hours. It leaks within this window. Is it because the siz eid small or because it is defective?

A. it s tight . can use any brand of diaper like pampers Huggies many Poko baby hug what ever suits baby skin all are safe . Diaper hygeiene is a must to follow . Change diaper immediately after poop or every 4 hour s to prevent any chance of infection . Use any baby cream over diaper area for rash .
