Ds is almost 2, and we still use it religiously.
He CAN get out of his own bed (he's in a real twin size bed) and stand at the door and yell if he needs us, but I am VERY thankful that we still use it - just 2 nights ago, I heard a cry through the monitor that wasn't "normal".
I go rushing in, to find that his body is on the floor, and his leg is trapped in his bed rail!! :shock:
Bedrail is now removed - if he falls, he falls onto the floor covered in pillows.
Glad we still use the monitor, or else I wouldn't have heard his cries!!
