Cleaning

How to keep the place clean?! I’m alone with a almost two year old and now 21 weeks pregnant I start cleaning and get so tired and sore. Do you have any tips on how to do it better? And organize things I don’t have anything to store stuff 😩 it’s like a constant tornado I’m a messy person and then having kids on top of it don’t help one bit but I’m trying to become cleaner so any ideas will help. I work full time also so it hard to have energy and I’ll be starting a cna course in a few weeks.
