Your 20-Month-Old: Arranging, Asking, Singing, and Standing Steady
By the Growbaby team · Published Aug 4, 2026
Written against AAP, CDC and WHO guidance. How we write these guides
At a glance
- Rows of objects get arranged, inspected, and rearranged with intent.
- Questions arrive: what that, where daddy, asked on repeat.
- One foot lifts off the floor briefly, usually with a hand on furniture.
- Familiar songs get joined, often only the last word of each line.
- Combs, cups and toothbrushes get used the way they are meant to be.
The lining up that appeared a few months ago comes back now with more purpose behind it. Rather than a row for its own sake, objects get arranged according to some rule your toddler is holding privately, and rearranged when the rule changes.
Questions start being asked rather than only answered, songs get joined in, and balance improves enough for one foot to leave the floor deliberately. Everyday objects also get used more consistently for what they are actually for.
What is new this month
Arranging objects has moved on from the earlier version. There is a plan behind the row now, even if it stays invisible to you, and anything that breaks the plan gets removed. This is the start of working to a rule rather than to an impulse, which is the foundation for sorting, sequencing and later for games.
Asking a question is a bigger shift than answering one. It means your toddler understands that you hold information they do not, and that words can retrieve it. The repetition can be wearing, and it helps to know that the answer often matters less to them than the exchange itself.
Singing along and standing on one foot are both about timing and control. Joining a song means predicting what comes next and arriving on it, which is why the last word of a line comes before whole phrases do. Balancing on one foot demands constant small corrections from the ankle and hip, so a couple of seconds with a hand on the sofa is a genuine achievement.
Week by week, in the app
Our paediatric specialist wrote one thing to notice and one thing to try for every week of the first three years. Here is what this month covers. The app works out which week your child is in from their birth date and brings each one to you on the day.

This week, for your baby
Growbaby works out which week your baby is in from their birth date and brings that week's activity to you on the day, so you are not looking up where you are. Plus adaptive soothing for the nights and Growy for the questions in between.
