Baby fingers/hands in mouth

Stacy

My 13week old will not keep her hands out of her mouth. I've tried to give her a pacifier instead but she's not into it. She's sometimes sucking, sometimes just playing. Sometimes if she's really into sucking her hand will turn red. She's not hungry, not tired, what gives? What should I do? I'd just rather her have a pacifier than be a thumb or finger sucker!
