Baby boy names

I need help!! My husband and I both like the name Theodore but can not come to an agreement on the shorter/nickname version. I love Theo but my hubby doesn’t and he likes teddy and I don’t like teddy at all. Neither of us like Ted. So we’re back to square one and need ideas. We already have a middle name picked out(it’s a family name that we are passing down and it starts with “k”) I also like names that aren’t popular but not crazy out there either. This is our second boy and we are running out of time. Our first boy is Anthony and we call him AJ.
