Mam bottles with prep machine

I have this with 5oz on the Mam bottles ! No idea why it happens x

@Eleanor as in your on number 4 on the prep machine and it goes to 5oz on the bottle? I have friends who make up there bottles and go by the bottle oz and don’t have a prep so they would have less water to powder ratio than us?! 😩

Its the volume of the powder causing the water to raise

@Kath but surely if you didn’t have the prep machine and made up bottles you would only go up to the 6oz line on the bottle therefore more powder to water ratio. Just wondering what line I should go up to on the bottle when I’m out and about, have been going up to the 7oz line to keep the same as the prep machine.

The water will always rise if you put the powder in after the hot shot. It’s definitely the powder because I don’t put mine in after the hot shot (different prescribed formula that doesn’t need this) and the water is accurate

I think it’s partly a fault with the prep machine. Mine did it too so I trialled making a bottle but didn’t put any powder in and it still did it, so can’t just be because the powder increasing the water volume.

@Chelsea you should add your water first when the formula so the water level will still rise

@Chelsea I have this with mam bottles, I have just assumed it’s to do with powder/shaking after the first hot shot. I imagine if you make with a kettle with no powder fill to 6oz (but I’m not an expert this is just what I’d do) x

I have this as well! I asked on here ages ago! General consensus was that if I’m clicking 5 Oz I’m getting 5 Oz of liquid despite it looking more like 6, it’s likely a combination the formula powder and also the bubbles! If you’re unsure that your machine is giving the right amount of liquid do a test run no formula just the water in a measuring jug and get right down on eye level to see how many Ozs it’s dispensing! i found that it was maybe a mm over 5oz but was the right amount!☺️

Hi guys, you’ll be surprised my health care visitor came around and saw I was using the MAM bottle and she told me the issue she had with it. They come with a default. She was realising that once she made the bottle and put it in a bowl of water to cool down the amount rose. What’s happening is the holes at the bottom of the MAM bottles is taking in water 😭. So now I’m not going crazy at people thinking they don’t know their numbers and just keep making extra Oz!

@Hamda you can resolve that by taking the lid off the bottle when you stand it in the cool water

The prep machine has a conversion chart under the lid where you fill the water. American oz and English are different. Im currently on 6oz and stop the prep and 6.5oz to account for the formula i added in the hotshot. My partner did loads of ‘tests’ with doing kettle bottles and prep and we noticed adding formula raises the oz amount by roughly half. So thats what we go with 🤷🏻‍♀️

@N 💞 ohhh I have not heard of that I’ll give it a try, thank you x
