Although there are some sources of information for parents on a movie’s suitability for a certain aged child, these are quite dry and sometimes it’s hard to decide without watching the film.
A website where each movie is graded by parents who saw it. Each such review should be as contextual as possible, giving the reader the points pro and contra, the personal experience and age group suitability based on their child. This way the reader will have a better filter to apply it to their own child’s age and personality.
Teach your children basic financial planning.
Create a simplified table for your kids to use, where the labels used for the different fields are from their own world in their “language.”
Make the visit to an exhibition more fun for the kids (and their parents.)
Write secret facts and stories specifically for kids for specific exhibits. These are only visible to kids if they wear special glasses, or flash a special light around the exhibit and find these secret writings.
Are video games good for your kids? Which ones?
A website that reviews video and other games and tries to find out what are the benefits for the kids playing those games (what skills they are developing, both physical and mental), and what are the potential detriments.
Help you protect your kids from drowning.
A swimming cap with sensors and communication unit. When the cap is underwater for a longer period (more than a few seconds), you get an alert on your device (smartphone, special receiver, etc.), so you can check on your child to make sure all is ok.
