Thank you, Jamie, for helping me with some modifications!
Question- Can I do shoulder taps from a kneeling push-up, or will that cause too much rocking?
Thanks!

Ahhh yes, Heidi!
This is another great option that will most likely not put your toes into extension (I say that to ensure that you are not circling your toes under when you have them on the ground- allow them to lie flat (top of foot) side down---or keep them up into the air with appropriate padding underneath!
You rock!
