2 car seats for toddler

posting for a friend who is a former Stanford post doc

she's giving out two car seats for free (pick up at south San Francisco). She can also drop off at Stanford for $40 (for 2)

the diono one is good for toddler younger than 4 yo and the graco one is good for 4-12 year old. The white stain on the graco one is from ethanol disinfectant.
