How to age up a toddler in The Sims 4
In order to age up a toddler in the Sims 4 you just need to get one of your adult sims to bake a cake. Once you have one, click on it to select it and choose the 'add candles' option and 'have [toddler's name] blow out candles.'

How to earn toddler reward traits in The Sims 4
To increase your chance of earning toddler reward traits, you'll need to focus on helping your toddler with five different life skills: Imagination, Communication, Movement, Potty, and Thinking. Potty is important for obvious reasons, and the other four all correspond to a skill for the next stage in life, child. For example a toddler with good Thinking skills will have better Mental skills as a child. Building these skills is really just a case of good toddler care - make sure they are clean, fed and watered, and interact with them a lot. Read to them, lecture them when they misbehave, and fill your house with toys.
There are three skills levels for Potty, and five for Imagination, Communication, Movement, and Thinking. If you get all of your toddler traits to at least a level 3 you will get the happy toddler reward trait when you age up to a child. This makes Sims learn new skills faster, which is a handy buff whatever your future aspirations may be.
If you get Imagination, Communication, Movement, and Thinking to level 5 (and Potty to level 3), this will earn you the top-notch toddler reward trait when the Sim ages up to a child, and will make them learn new skills even faster than with the happy toddler reward trait. You can also skip all the hard work with some Sims 4 skill cheats that let you manually alter toddler skill levels.
