If, like me, you struggle to tell when your baby's bath water is just the right temperature, then you really need one of these. It's a Philips Avent Bath and Room Thermometer and it's just £9.99 at Amazon right now, down from the usual price of £18.00.
This can be used to monitor room temperature as well as the temperature of bath water, so it's a handy thing to have around for checking that your baby isn't overheating. You can float it in the bath or just pop it on a shelf (out of baby's reach, obviously) in your little one's room, and the accurate digital measurement will keep you informed of when it's time to pop an extra blanket on or remove a layer of clothing.
I am convinced that keeping my baby's room at the right temperature helps her sleep better; she's definitely more likely to wake if she gets too warm or too cold, so this would definitely be one of my 'must-have' items of baby gear.
Delivery will be free if you're an Amazon Prime customer, too, and if not you might want to add some extra baby essentials to your basket yo avoid paying for delivery.
