My little girl was trialled on SMA Althera as they suspected it could an allergy, it was very similar to preparation to regular formula. I’m not sure which one you have been prescribed but you can always double check the tin/ their website which should have preparation/ feeding guides.
But here’s what I do with our formula, hopefully it helps and gives you some guidance.
Once made up how long out the fridge?
Once freshly prepared the formula either needs to be placed in the fridge or must be used within 2 hours. If baby has started drinking from the bottle then it’s 1 hour from when they started.
How long in fridge?
Formula can only be stored in the fridge for up to 24 hours.
Do I need to warm it up when I take it out fridge?
No you don’t need to warm it up from the fridge but some babies may prefer it warmed up, depends on your little one.
What do you do during night? Take it from fridge from previously made? Or make it up when needed?
At night time we use our Nuby Rapid Cool, which we wash after making formula and place into a Milton cold water sterilisation tub. Alternatively you could use previously made bottles if baby is happy drinking them cold or you could warm them up first.
You can warm them up using a bottle warmer or a put the bottle in a jug of warm water. I’m not sure if you are using MAM bottles but if you use the jug method you will need to remove the lid to stop water being sucked up through the bottom.
When going out for day how do you do it?
Going out for the day, again we use the nuby rapid cool if it was just for one bottle. Or you can take previously made bottles out in a cool bag with ice packs (this is only for 4 hours). Or some people take a flash of boiling hot water and one of cool boiled water to mix on the go.
Also how many mls does a 3 month need a day and in feed? She's only 8lb now (has had lots of medical problems so very small)
The tin should be able to suggest how many mls to offer. I think when my baby was 8lb she was having 4oz every 3 hours but some babies will want less or more.
Hopefully that helps you a bit, when I had to give up breastfeeding and move to formula feeding. I did find the NHS website quite useful. 😊
