hey its all normal...
mine has been moving heeeaps lately...and its more active after dinner, all through the night, everytime i turn or move in bed it moves too, and if i lay on my left, bubba falls to the left side, and when im on my right side, it falls to the right...
its actually very weird how quick it can change position...

Ive has very strong scraping movements in my sides, like someone is scratching me inside with their nails...

lol
