Does anyone have experience with a Boba carrier, specifically the 4G. I've been really wowed by all the positive reviews. I also like that you don't have to purchase a separate infant insert. Has anyone used it with an infant? I would like to use it for some hands free time in the house in addition to walks, etc. Do you think it is good for around the house? Will I regret not getting a wrap? I'm a total babywearing newbie! Help me out!
