I will not 'knowingly' release a child if they do not have the proper car seat ... its right in my handbook that anyone picking up the child MUST have the proper restraint system in the vehicle if not the child will not be released and any 'late fees' would be charged until someone could show up with the proper restraint .... the other option to avoid a late fee would be to walk home, take a bus or call a cab which as 'public transit' do not require car seats ... my clients all know I am a certified carseat installation technician and therefore am anal about car seat safety!

If you are not sure I would open a dialogue with the client and ASK ... if she claims she has one and it is a mistake by the child and you are still not 'sure' I would watch to see she put her in one and if she DID NOT than I would call the police and report that while you tried to inform the client of the dangers that a child just left your premises with the child not properly restrained and they will send a car to either 'educate' her on the risk or ticket her .... this is what we had to do in centre care when we saw people not properly and legally restraining to reduce our liability as we are legally required as professionals to report suspected 'neglect/abuse' of a child and that is definitely neglect ... at least than you have done your due diligence if the kid gets injured or killed between your home and her own because she was no restrained properly in the car you did everything within your power to prevent that!
