Heavy sleeper

Emily

Mommies, I need some advice and possibly some suggestions on how I can train myself to sleep lighter. I have a newborn and I am a heavy sleeper. Last night, my baby was crying hard while my grandma was changing him and stuff(she’s been staying for a couple nights) and I never woke up to it, she said I slept through it all and that is so scary to me. Is there anything I can do?
