Lost first time mom needs help!

may

My baby is 2.5months old now. Im very lost now. He now stretches his sleep 4hours be it night or day time but his milk intake remains at 120ml. His weight is 6.14kg now. Should i wake him up for regular feeding? Is he eating enough? What kind of day time activities should i do with him other than tummy time and letting him grasp on different things and exposing him to different texture? Me repeating the daily activities everyday will he gets bored? What kind of development should i be expecting from him at this stage? Please help me
