Digestion process is really REALLY slowing down....

I drank my milo...and some plain water..i burped...IT WAS THE VEGGIES SMELL THAT I ATE AT 6PM. 5 hours and still in my stomach??? Compared to last time every 2 hours i feel hungry...my digestion is really slowly down to let baby absorb more...woah.....baby is damn active after I finished the milo...sugar high!!!!!!
