It can definitely just be the baby and/ or where the placenta is. DS1 was active, this one is active, DS2 was a very sedentary little blighter, I honestly very very rarely felt him throughout pregnancy. It is stressful, I had forgotten until this one just how stressful, but this one, despite being my third and me therefore being even busier, each evening once I sit down regular as clockwork she starts kicking (or I'm quiet enough to actually notice it at any rate
)
