Sterilising

Yes everything milk touches and babys mouth touches needs steralising, dependant on what bottles you are using and pump for the steraliser, I'm expressing a bottle feeding as baby struggles to latch properly, I was using a second hand tommy tippy and it was relatively good, could get 6 mam bottles done or the pump steralised, i got rid of it only because it kept tripping out and I wasnt sure it was running a full cycle, however baby drinks better from doctor brown bottles so I bit the bullet and brought the steraliser bottle set in their sale and it's brilliant, steralises and dries.

I'd say if your looking for a steraliers make a list of its must haves like efficiency rating, how long uts cycle runs ect and go by that xx

You can get a Milton cold water steriliser really easy to use xx

My HV told me that the pump just needs to be sterilised once in 24 hours and can be left in a Tupperware box in the back of fridge in between uses.
I haven’t personally followed this advice, but maybe something to check with your HV to save yourself some work - if it’s a thing.

Breast pump only has to be sterilised once every 24hours not after every use. Several midwife’s/HV have mentioned this to us as we are exclusively pumping as my daughter decided to refuse to latch after 6 days of BF
