Clipart needed for cutter.

I am making a sign for a Daycare Center that watches babies to adults with special needs. The owner wants clipart on her sign that shows a progression from baby to toddler to teenager to adult. Does anyone have any ideas where I can find this. I have some OCA disks at the shop but I am working from home today. I'm not sure if they have anything I might be able to use. Any help would be appreciated.
