First time Haaka

I’ve had it for ages but just finally had the chance to use it for the first time. Got an oz from my slower side while he ate. Can I save it and add to it from the next feeding before freezing or does it have to be frozen separately? Side note I also set it on the counter and knocked it over so... 3/4 of an oz remains 😒😑☹️
