Lazy baby is scaring me!

Rachel
Normally, my lil man has spurts of being super active every 3-4 hours. Sunday, he wasn't super active, but was rolling over regularly. Monday was normal. Tuesday he was quieter, but still active with rolling. All night when I would wake up, he was quiet, which he usually dances when I lay back down. Today I had to drink 24 ounces on ice cold lemonade to get him going this morning, and just a few minutes ago I ate a whole pint of ice cream and he is making little punches and moving his feet a little.
I don't know what to do! Is he resting because labor is near, or should I just chock it up to him being lazier?
