Price is also likely to be a motivating factor, with monitors ranging from £20 right up to £200, with a decent, mid-range option costing around £60.
But try not to be distracted by frills - lullabies and light shows can be impressive, but you’re buying peace of mind while your baby sleeps, so prioritise key functions before succumbing to endearing additions.
Then there’s the technology – do you want interference-averting digital or analogue?
Some argue the latter avoids the long-term effects of microwave radiation from wireless technology on the developing brains of children, although scientific studies have yet to prove a link (also, remember that most houses hum with invisible waves already, through wi-fi, mobile phones and so on).
When it comes to baby monitors there’s an overwhelming number of options, brands and models, covering all sorts of functions you never knew you needed (and quite often don’t) - choosing the right one can be perplexing.
