Can anyone help/advise on this please.
I have been given a set from the midwife with syringes etc and have given it a go, only got 0.2ml 
How long can you add to a syringe before it needs to be frozen?
How much do you typically 'need' to go to hospital with?
How do you get more out? 😂
Sorry, I'm a massive beginner at this!
