Easiest way to sterilise bottles?

Milton cold water steriliser. You fill it up with water from the tap, put a Milton tablet in it, and put your washed bottles in it. In 15 minutes the bottles are sterilised. You change the water and tablet every 24 hours.

I agree with Kira. I just bought a storage container out of asda which had liter marks on the side (im not too sure how big it has to be as my LO is 23 months now, but im sure my box has a 6L capacity and it has a mark at 3L as well.) You just fill it up with cold water up to the desired mark and add the desired amount of milton tablets. You can sterilize a lot of stuff all at once this way. Just make sure to wash everything beforehand. You can even add things throughout the day, say a dummy fell on the floor and needs sterilizing. Just give it a wash and pop it in for 15 minutes and its good to go 👍🏻
