Little ones don't always understand the concept of time, so getting them on any sort of routine can be difficult. This custom clock, however, can tell your toddler when things are going to happen throughout the day, and help them learn how to read a clock.
This clock modification, from Instructables user benbrandt22, uses a cheap, battery-powered clock that cost only about $5. You can probably find one at a store near you for about the same price. Once you have the clock, you just have to design and print (or draw) a new clock face that clearly explains what your toddler's day will be comprised of.
You can then replace all the clock hands if you like, or just the hour hand to keep it from being too complicated. When it's completed, you can hang it in their room or play room so they know when they will get a snack, when they have to take a nap, and when it's time for bed. You can find the complete guide at the link below.
