Crawl! My nephew was breach so my sister in law crawled around the house a bit &it worked turnes him around.
Spinningbabies for sure. And if that doesn't work, push to try an external cephalic version early, like at 37 or 38 weeks. A lot of OBs won't mention that option till quite late, but it works best before baby is too big.
33 weeks is still pretty early. He may still turn on his own you still have 6 weeks left.
Have a look on the spinningbabies website.
