Breastfeeding must haves

Le

Not a first time mom but planning to breastfeed this time. I’ve been trying to educate myself as much as possible before hand.

What are some of your must have nursing/breastfeeding products?? What can’t you live without? What was a waste of money?

I will be returning to work at 12 weeks pp and plan to pump at work while baby is at daycare. Any advice for breastfed baby attending daycare?
