Hi, looking for peoples opinions on methods of sterilising. Wee man keeps getting thrush which cleared up but is coming back. We use the microwave to sterilise his Mam bottles which are self sterilising. My partner was looking into the Milton cold water steriliser and I've done my calculations on the cost which works out cheaper. But I want to know if it makes a difference at all and if cold water sterilising is easier? She also mentioned about the Milton washing up liquid but tbh I am not sure about that as surely standard is good enough? I wash and rinse in hot soapy water throughly anyhow.
