I have multiple carriers that were all hand-me-downs. Our 7 week old will only contact nap so we are trying to find a carrier he likes. So far we tried the moby (getting the fit right was hard and he screamed both times we tried!), k’tan (again he screamed!), original baby bjorn (he liked when I went for a walk with it (constant movement) but has cried multiple times when just doing stuff aprons the house). We still have the Tula ready to grow and ergo baby with infant insert we haven’t tried yet. For a tiny baby (only 9.5lbs at 7 weeks) which would you recommend for the purpose being constant naps while I get stuff done around the house?
