Do whatever you'd like. Collect don't collect. Totally up to you.
Probably 4 hours then freeze
I use the haakkaa ladybug milk collectors. I like that they fit in my bra and that they aren't actually pulling anything out. Just catch what leaks! 😁
You can definitely collect with a syringe as long as you’re not actively expressing (as you know!) I was told to put the syringe in a freezer food bag and label with the date :)
Are you leaking colostrum or milk?
