One thing I hope this Support List doesn’t leave out is having a backup set of pump parts. 
I learned this only after I started pumping regularly. I never realized how much time I would spend washing, drying, and putting pump parts back together — and then suddenly needing to pump again while everything was still wet!
Having an extra set changed my routine completely. While one set is being washed and dried, I can use the clean set without delaying a pumping session.
It may sound like a tiny thing, but when you are pumping several times a day, those little moments of stress really add up.
My tip: if you pump regularly, keep one complete clean set ready to go. It makes pumping feel less like another chore and gives you one less thing to worry about.
Sometimes the best breastfeeding support isn’t a big solution — it’s one small thing that makes a hard day a little easier. 
I did this and it’s been such a relief also so good incase something malfunctions
