It's normal, it happens with the perfect prep too once you go over a certain amount of Oz. As long as you know you're using the correct amount of water to formula you're fine x
It's the formula in the water that makes the level go up but as long as you're measuring the right amount of water its fine 🙂
Oh wait? You’re still meant to pour the full amount of water in the bottle? 😂😂😂 I was just measuring to the 160ml mark and discarding the rest hahahahaha
It’ll be the formula in the water making it rise above the level. The prep machine does start doing this too when the feeds get bigger. My boys on 7oz and on the mam bottles it’s closer to 8.
