Learn when babies use stacking cups and how to adapt play from grabbing to nesting. A stage-by-stage guide with practical stacking cups play ideas for 6 to 18 months.
Quick answer
Start with Montessori baby stacking cups as soon as your baby can sit and grab, usually around 6 months, and change the challenge as they grow: bat-at and transfer play first, then nesting, then stacking and pretend play. The cups stay useful for well over a year, so buy once and adapt the setup rather than replacing the toy at every stage.
Why stacking cups stay in rotation longer than most infant toys
A set of nesting cups is really several toys in one: a teether, a transfer toy, a nesting puzzle, a first stacker, and later a container for pretend play. That range is why the same set can serve a 6-month-old and an 18-month-old without feeling babyish to either.
The trade-off is that cups reward a little adult setup. Left in a pile, many babies swipe once and move on. A short, stage-matched invitation—two cups, one soft ball, a shallow tray—gives the play a clear next step.
Match the stage, not the birthday
Babies reach these stages at different times, so use the descriptions below as a rough map. A baby who is not yet sitting steadily will get more from mouthing and tracking than from nesting. A toddler who already stacks confidently needs pretend-play prompts, not simpler stacking drills.
Watch for signs of readiness rather than pushing the next stage: reaching for two objects at once, deliberately dropping one item into another, or trying to balance a cup on top of something.
- Around 6–9 months: grabbing, mouthing, banging, and moving a cup from hand to hand.
- Around 9–12 months: putting objects in and out of a container, and exploring size differences.
- Around 12–18 months: nesting cups inside each other, stacking two or three, and early pretend play.
What to check before you start
Silicone cups are soft enough for mouthing but can still be heavy when a baby swings them. Clear a floor space, check that no cup has a tear or split, and keep the set away from hard tile edges during the throwing phase.
If your baby is still mouthing everything, handwash the cups with warm water and mild detergent, then wipe dry or air dry before each session. Avoid leaving them soaking, and inspect the rims regularly.
Stage-by-stage play steps
- Step 1: Set up a grab-and-mouth invitation (around 6 months): Place two or three cups on a low tray or blanket within reach while your baby is sitting supported. Let them bat, grab, mouth, and drop the cups. Narrate what happens: 'You dropped the green one.' Common mistake: offering all seven cups at once, which scatters attention. Checkpoint: your baby reaches for or mouths a cup without help. Keep only two or three cups out until your baby reliably reaches for them.
- Step 2: Add in-and-out transfer play (around 9 months): Show your baby how to drop a small soft ball or a smaller cup into a larger cup, then tip it out. Use one large cup and two smaller ones. Common mistake: using objects small enough to be a choking hazard—stick to the cups themselves or a ball larger than a toilet-paper tube. Checkpoint: your baby puts an object into a cup and looks for it to come out. If your baby only bangs the cups, stay at this step a little longer before introducing nesting.
- Step 3: Introduce nesting (around 12 months): Hand your baby two cups of clearly different sizes and show one going inside the other. Let them try, and resist correcting every attempt. Common mistake: starting with the two closest sizes, which are hard to tell apart. Checkpoint: your baby nests at least two cups without your hand guiding theirs. Work up from the largest and smallest cup first, then add middle sizes.
- Step 4: Move to stacking (around 12–18 months): Turn the cups upside down on a flat, stable surface and stack two, then three. Sit beside your baby and stack slowly so they can watch the balance point. Common mistake: stacking on a soft rug or bed, where cups tip constantly and frustrate the child. Checkpoint: your baby places one cup on another and leaves it there. Use a hard floor or low table for stacking sessions; save soft surfaces for mouthing and transfer play.
- Step 5: Add pretend play and language (18 months and up): Use the cups as bowls, hats, or scoops in pretend play. Ask simple questions: 'Which cup is biggest?' 'Can you fill the blue one?' Common mistake: turning it into a quiz with right and wrong answers. Checkpoint: your toddler uses a cup in pretend play or compares two sizes without prompting. Retire a cup from the set if it develops a tear or split, even if the rest are fine.
Product facts

Montessori Baby Stacking Cups - Montessori Baby Stacking Cups: Each cup is about 3.53 x 3.53 x 2.56 inches and weighs 9.9 oz for the set. The size is easy for small hands to grip, but the set is light enough that a thrown cup is unlikely to be a heavy projectile.
