Today's nursery paging system has changed drastically in comparison to the techniques used just ten years ago. There's no longer a need for a nursery volunteer distracting the worshippers and service to alert a mother that their child needs them. New technology has now made this obsolete. Now parents are given a personal pager after they drop off their child. A parent is issued a vibrating pager when they check their toddler into the nursery. If a parent needs to be summoned by a nursery volunteer during the worship services,, they merely key in the number into the transmitter and as a result the parent is instantly notified. It is as trouble-free as that.
