I think some of your items are too low. A baby sweater for $10? Other shops are selling them for twice as much.
I sell my coffee cup cozies for $7 and that prices has never hindered me selling most of them (I actually need to make more. . .).
In the more recent past I had to raise my prices on some items because I realized I couldn't make money on them. I was selling my hats for $15 and they barely sold. I raised them by (some by $10, others by $15, depending on the type of yarn used), and I actually sold some, and people didn't flinch at the price.
Are you working on your off Etsy marketing? Maybe that will help with moving some of your items.
