Our daughter keeps "chewing" (more like gumming lol) on her hands even though we've fed her. She's almost 3 months on January 6th..We fed her 6 oz already (not all at once)
Look into teething mitts. We started teething aroun two or three months but he didn’t cut any until six or seven.
My son started teething at 3 months but nothing actually popped through untill 6 months. He would chew his hands and feet.
They can teethe for a long time before an actual tooth comes through. It could be that or she’s just doing it for comfort like a pacifier would.
Doesn't have to mean they are hungry or teething. Babies just like to chew on their hands, they are figuring them out lol
