Does anyone have any suggestions for a good carrier for a 2 month old who hates being in the ERGO carrier? I have tried it with and without the Heart2Heart insert and he freaks out. I think he doesn't like having his legs apart. I was thinking about geting a ring sling, which I think would solve that problem... Any brand recomendations? I'd like to get something sturdy, he's an active, wiggly little guy! TIA!
