What makes baby move the most?

PC • Mama to Cruz 💙 Kaia 💖 and Shaea to come 💗
Im almost 22 weeks and am finding I feel him the most (like a little ninja) when I'm hungry. When I eat and I'm full, it's like he's in a food coma. Like clockwork lol 
And when I have tea = caffeine. 
Have you found a pattern yet in things you're doing? Apparently at this stage they respond to light and noise, but I have yet to really feel a difference there.
