If you have a baby, you know how difficult it can be to tell what they want. Whether they’re hungry, hot, or need to be changed, the only way they’ll let you know what’s up is to cry uncontrollably. Sadly we don’t have any crying translating devices floating about, so we’ll just have to enlist the help of science to fill in the gaps.

Something that is almost a constant concern is whether or not baby is sick, or running a temperature. This is where the BabyGlow swoops in to give you the peace of mind you desperately need. This little pink or blue onesie changes color any time your little one’s temperature gets too high. It will change from its normal color to a blotchy white, letting you know what’s going on long before they start to fuss. This doesn’t mean that you will be able to stop them from crying completely, but you will be a little ahead of the game if they’re starting to get sick. It only costs about $40, and is machine washable.
