Turn into light sleeper 😯😯😯

I know it sounds selfish but I'm so sad that I'm turning into a light sleeper now that I'm pregnant and I know it's only gonna get worse once my baby arrives in the next couple weeks... I used to sleep thru everything.. Storms, trains, earthquakes, TV being turned on, you name it. Now everything wakes me up. Even the dog walking past my room. Ugh I just a solid nights sleep one last time. Before I don't don't sleep for the next 18 years lol
