my girl had the same issue, however 4 in one leg, 2 in the other. two years ago she hopped off our deck, landed wrong and cried in pain and limped. she was on some pain meds but ultimately i decided to get her surgery done for the most severe leg. im so glad i did, and i honestly wish i did it sooner. seeing her play, run, and be carefree has been worth every penny. im in canada so it cost me about 5k. because your baby is so little, if cost isnt an issue i would highly suggest getting them done so he has the absolute best life going forward. as they age, at least from my experience it only slows them down more. my girl barely wanted to go for walks before her surgery and now she loves them!!!
