Genuine question about motherhood

I’m almost 7 months pregnant and everyone keeps telling me to enjoy hot coffees and showers/baths while I can. Am I just being really naive but don’t babies sleep quite a lot especially near the beginning? We’ve got a Moses basket for the living room so surely I can put her down for 10 minutes to have a coffee, no? 😅 I also have a husband so fully plan on showering every day before he goes to work

Am I being stupidly naive about motherhood?!
