How long is breast milk good for once wcm has been mixed in with it? How long is it good for once DD starts to drink out of the sippy cup it's in?
For example, she spent a half day at daycare today and brought home a nearly full sippy cup of bm/wcm mixture. Can I send this to daycare with her tomorrow? She's 12 months and we are working on transitioning her over to WCM for her daycare days.
