Baby less sleep

Hi all. My baby nearly 2 months old now. Just to make sure, my baby didnt get much sleep between 8am to 5pm, does this mean her sleeping time change? Usually 6 hrs. 2-3 hrs every time she slept. Now its less than 1.5 hrs every nap. But she will fall asleep at night straight 3 hrs (between 6-10pm)
