It has been reported via a blog written by Sim Guru Ryan, in the base game for Sims 4 the different life ages. To the surprise of many, the toddler stage isn’t included.

•   We are also very excited about our new Create A Sim! You probably guess this since we’ve been showing it off everywhere. We’re particularly proud of our new Genetics system, where you can create relatives from any other Sim. It’s like a game in itself! As for ages, we have babies, children, teens, young adults, adults and elders. With our new personalities, you can really feel how their individuality plays out in the gameplay. We can’t wait for you to try it.

To add insult to injury the young adult, adults and elders life stages are all the same height. Bummer guys!!

It’s been said that EA have announced that toddlers (and pools) will be added at a later stage.

I’m a little split with how I feel about this. On one hand I’m excited to be able to click and drag in order to create new sims, it looks like a much nicer, cleaner way to do things without the use of sliders. The build tool looks amazing. However, it feels as though they’ve gone overboard with the creation and are leaving out the game play. Although, the game play can (and probably will) be expanded upon with the inevitable plethora of expansion packs that will come out afterwards. So I feel that it’s OK to focus on the game play and creation in the base game because that’s something we’ll all be doing a lot of.

The toddler stage (and pools) were something that I enjoyed having, but didn’t use much. I often zoom through the toddler stages anyway, they don’t really do much as toddlers and pools often got in the way with Sims wanting to swim in the middle of winter, at night.
