Any advice appreciated - I have a tommee tippee prep machine I used it for my first child 8 years ago I’m due my second in a few months will it still be okay to use with a new filter and cleaning cycles or do I need to get a new one ? I have taken the back off and all wires are in tact and no mould or anything what so ever - I did thoroughly clean it through and used clean cycles before it was stored away also
