NEW YORK - Keeping tabs on your baby just got a little smarter. 

New devices have hit the market that pair with smartphones, including an ankle monitor, and a onesie that can track your little one's breathing, heart rate, temperature and sleep patterns. 

The technology can alert parents if there's an issue with their child; however, not everyone is on board. 

Some health experts say they worry parents will become too reliant on monitors instead of their own intuition.
