When will baby kicks be able to be felt on the outside of my stomach?

S • mama to a babygirl 💗 expecting baby #2 in May 💞

I’m a plus size ftm w/ anterior placenta. I started feeling movement at 19W5D and started feeling kicks 20W1D. I’m now 20W3D wondering when the kicks will be able to be felt on the outside of my stomach; AKA, when will my SO be able to feel the baby kick?
