Baby sleep

Bailey

My baby seems to wake up easily when he sleeps at home he will fall asleep in his car seat on rides but then wakes up again when we are at the destination. I don’t want to have to always tip toe around so he will sleep. What do I need to be doing? He’s only 11 weeks old so do I need to be doing something now or do I start when he’s like 4 months? When he was a newborn I made sure to vacuum while he was asleep and he could sleep through anything but now he can’t. I do use a white noise machine though to make sure it’s not silent. Any advice would be appreciated (:
