Ive got avent microwaveable sterizer and I'm slightly confused. It fits 4 bottles and instructions says stays sterile for 24 hours as long as lid is not opened.
Now seeing as u can only use one bottle at a time the minute you open the main lid does that mean the other bottles can't be used??
Sorry if this seems like a dumb question but my baby is 2 days old and I want to be doing everything right xx
