So... I'm obviously an idiot. It never occurred to me not to leave things in the steriliser. I thought the stuff was clean and sterile so I could just leave it. I was wrong.
I went away 2 weeks ago and had left my sterilised breast pump in the steriliser only to open it today and see mould on my breast pump. It is an electric one so it was kinda pricey so I've tried to clean it but I'm still not sure that it is safe to use. I've washed it, sterilised it in the microwave, washed it again (in the process of actually), then am going to sterilise it with those tablet things and then perhaps wash it again. But will this be enough?
I really can't afford another pump right now but I definitely can't put my daughters health at risk for any amount of cash...
