Because babies don’t just sleep in cribs, The First Years designed the first monitor that attaches to almost any place. This monitor gives you the flexibility to attach the child unit to most cribs, carriers, strollers, swings and bouncy seats so you can monitor your baby practically everywhere. The parent unit has a belt clip allowing parents to move around but still hear baby. While many monitors allow you to attach the parent unit to your belt, this is the first monitor with a portable child unit that can be attached as well!
