Hi Would like to check how do you all sterilise bottles when overseas? Is there a portable steriliser to bring along or do you all use the tablets (seems abit unsafe when dont need to wash off the chemical after soaking the bottles?)

I been using quick boil for their bottles or lugged a jumbo size lock and lock and sterilised bottles in it. Did it a few times when kids was admitted into hospital as kids preferred to use own bottles and teats. Used sterilising tablets once and that's it, I will not be using as it gives out the chemical smell which kids dislike.
