The box contains five capacious, well-designed bags that can fit two bottles apiece and each bag can be reused 20 times, so they’re much more economical than they might first appear. Cold water sterilisers involve filling a container with water and adding sterilisation tablets or fluid to make a sterilisation solution. The active ingredient is sodium hypochlorite, which is a mild bleach that has been through a purification process to make it stable and non-toxic. It’s perfectly safe to use, but does smell vaguely of swimming pool. Finally, she looked at whether the steriliser represented good value for money considering the features it provided for a wide customer base, noting whether or not she’d buy another if the sample model broke. Most of them are cup-shaped microwave sterilisers large enough for one bottle or one breast pump – though you might not always have access to a microwave when away from home so look out for ones that can be used with cold water solution as well.

What makes a steriliser safe?

Relatively new to the steriliser market are UV sterilisers, which use UV light to kill bacteria. Their versatility means that you can use them to pretty much sterilise anything, including mobile phones and keys, however some UV sterilisers may not be suitable for sterilising natural rubber and latex (think certain dummies and the ever-popular Sophie La Girafe). If you’re bottle-feeding or expressing full-time, you’re likely to get through a large pile of equipment in a 24-hour period and you don’t want to spend all of it refilling the steriliser.

Nine months on, I almost exclusively breastfeed but regularly pump and often travel, so I’ve needed different cleaning methods for varying scenarios. Tommee Tippee has put a great deal of thought into the redesign of their electric steam steriliser and it really shows. The Tommee Tippee Super-Steam Advanced Electric Steriliser is made from tough BPA-free plastics and is exceptionally straightforward to use, with plenty of room for bottles and breast pump parts over two tiers.
