Frequently Asked Questions
What are toddler trays?
Toddler trays (sometimes called tot trays or tot school) are simple activity invitations set up on a tray or in a divided container. Your toddler works on one at a time, which keeps things focused and low-mess.
Where do I store all the tray materials?
A few clear bins or a small shelf work great. Keeping pieces sorted makes it quick to set up a tray when you have a spare minute.
What if my toddler dumps the tray instead of doing the activity?
That is normal for younger toddlers, and dumping and filling is its own kind of learning. Show them the activity once, then let them explore however they like.
