Can’t keep house clean

I’m fairly OCD and I want everything perfect for when our baby comes home. Trying to keep the house in pristine condition at all times in case I go into labor unexpectedly is impossible with a two year old, 16 year old and hubby 🤯😤. It’s so hard for me to get it the way I want being very pregnant and having SPD and it doesn’t even stay this way for more then a day. Any tips or tricks you other mommas have are welcome. My husband try’s to help as much a possible and neither him nor our sixteen year old are messy but our toddler..... oh my gosh, she’s a MESS!
