Amazon have the Learning Resources Pretend and Play Doctors Set on sale for £23.39, reduced from £36.99. Other versions are available for different prices, but for the the Learning Resources one, this is about the best price, it seems.
This doctor kit features enough medical tools for a whole team of young "doctors" to play at the same time. The sturdy plastic 19-piece set includes a battery-operated stethoscope, pager, realistic-sounding cell phone, forceps, band, thermometer, bandages and more.
Everything fits into a handy plastic clamp-tight case for portability and storage.
The cell phone requires two AA batteries, not included, so if this is to be a last minute Christmas gift, make sure to have some one hand, and to order next day delivery by Monday.
