Your kid's not old enough to one-button dial you on their Leapfrog phone, but you still want them to eventually find their way home at the end of the day? No problemm.
Wit the Philips SBC SC605 In-Touch Address Recorder, there's no need to keep your kids locked up in the house while you go out. Just record your home address, maybe a contact number--nothing longer than 20 seconds!--in this cute little pendant, pin it on your child's outfit (preferably in a place where burglary-prone pedophile kidnapperes won't spot it), and kiss all your worries goodbye.
If you're unconvinced, you can always stick a $20 in your kid's shoe and train her to play the recorder for the cabbie. [note: this might only work in NYC, where children learn to hail a cab before you even switch the Bugaboo from bassinet to seat mode.]
