We're trying to get our little girl a little used to bottles since I'm sick and may need some help but she really hates using bottles and I tried to pump one breast so that the milk is like fresh and hold her close to me to see if it would work which didn't for the most part she ate a little bit but then refused the bottle. Is it ok to store it after I try it with her if it's freshly pumped? I know you're not supposed to re freeze the milk or anything like that but in this instance would it be ok to store after trying to use?
