Baby sleeping more and feeding less

Hi, My LO is also around 2 months plus. I having this issue too except for sleeping more in the day( cause i felt the same still) for what i know they can sleep 5-6 hrs stretch around 2-3 months. As long as your baby weight is ok within the range its okay. however im still more or less worry about her intake as well. But nurse told me that baby know when they are full.

Try feed baby every 2 hr plus to 3hr
