Take one baby’s bottle + teat + cap….
Now, after use (feeding the baby) one is supposed to sterilise these items. The recommended way I’ve used successfully for the past 10 weeks or so is to boil them for 5 minutes in a saucepan.
So. Find saucepan, add water, put on stove top to boil. When timer goes off, turn gas down to low and get distracted cleaning up the kitchen. Go to bed.
Wake up next morning and wonder what the smell is from the kitchen…. Oops.
