Exclusive pumper - a must have
Bought this while exclusively pumping for my little one and it was a must have for the entire year. Bonus that it's pretty and easy to clean!

Lovely
Very pretty and easy to use. I’ve gotten a lot of use out of this ruler as my size has already changed a couple times during my breastfeeding journey!
