Frequently Asked Questions

How many ounces of milk does each Milk Bag hold?

Willow's spill-proof Milk Bags hold 4 oz of milk.

Can I reuse the Milk Bags?

Our Milk Bags have a one-way valve so milk comes in and doesn't come out. They are already sealed when you remove them from the pump, making them one-use only. This also means you can pump and store in the same bag without having to transfer your milk. You can store it in the fridge or freezer until you're ready to use the milk. Our Milk Bags are single use and should not be reused.

Can I pump with the Milk Bags and the Reusable Containers?

Yes, absolutely! Switch back and forth- and choose the option that is right for your pumping situation.

User questions & answers

Question:	The package says not to put in the dishwasher but I'm lazy. Has anyone used a dishwasher for a while and found their valves still work
Answer:	Hello typically you can play DVDs on a computer but it has to be a DVD drive. Sometimes it will have DVD written on the drive cover (where you put DVD in) or you can test with another DVD you have at home. If it plays these DVDs will play.
Question:	Are the color differences purely aesthetic or are they different designs
Answer:	I got it on Amazon.
Question:	Do you have to wash these after each use
Answer:	Approx. 60min each DVD. The DVDs are broken down into segments. So one DVD has several segments and all the segments that are add together equal Approx. 60 min. I hope this answers your question. Have a great New Year
Question:	How do I know when these need to be replaced
Answer:	Hello, these exercises are for active seniors. They are a good workout so it really depends on the skill level of the 87 year old. I would recommend visiting Youtube looking up Curtis Adams senior exercise to get a feel for the workouts. Hope this helps!
