Frequently Asked Questions

What ages are the Cub Cups suitable for?
We recommend 12 months and up, but it depends on the coordination of your individual baby. Some can start sooner, others later. Pediatric dentists recommend avoiding sippy cups altogether (the sucking and biting on spouts can adversely affect this critical stage of teeth and mouth formation). It is recommended to start transitioning straight from breast or baby bottle into regular cups. The sooner, the better.

How do I train my Toddler to use the Cub Cups?
The best way to help a toddler learn to use the Cub Cups is to let them make mistakes safely with it. We recommend starting with your toddler seated, and Cub Cup 1/4 full with water. Gently assist your child with lifting and tilting the cup to their mouth to drink until they become accustomed to this new coordination skill. Encourage them to use both hands in the beginning. They will naturally transition to one hand as they gain experience/confidence. Slowly increase the water volume as they become more comfortable with drinking this way.
Expect and allow spills! This is a valuable part of the learning experience as they see the consequence of being rough, silly or careless. A gentle “oh no!” and giving them a small towel to help clean up the spill helps the learning process along. For kids that are making frequent spills while seated at the table, it may be worthwhile to hand the cup to them to drink and when they are finished, place it towards the middle of the table, out of reach of clumsy elbows and hands.
Once they are comfortable lifting and drinking, we recommend keeping the cups on a low table or shelf in the kitchen or dining room where they can walk up, reach for themselves, drink and replace. To minimize spills away from the table, we recommend not allowing young children to walk around with the cups.

Are there lids for the Cub Cups?
Caveman Cups does not currently offer matching lids for the Cub Cups, however, they are in the works. In the meantime, we did some extensive testing with various silicone lids (including the thin, soft, stretch-over types like Boon). The only ones that were durable enough to withstand Toddler use (frequent hard-surface drops) were the Ucap Blossom lids in 3.5inch size. There are two varieties, the clear ones do not have any straw holes and are techinically “storage lids”. However, these can be neatly cut in the middle to accept straws of all sizes. The blue ones are identical to the clear variety, but have pre-cut straw holes in the middle. The Ucap Blossom lids in 3.5 inch size can be found from various sellers on

How do I clean and care for my Cub Cups?
18/8 Stainless Steel (aka “304 Grade”) is the highest quality Food Grade Steel there is. This is the same grade of steel used in high-end steel cookware. It is highly resistant to corrosion, however, it is not rust or stan “proof”. Contact with high levels of chlorides (bleach, chlorine, etc) or long exposure to acidic substances (lemons, limes, tea, coffee, vinegar, etc.) can cause stains or surface rust on 304 grade steel. Although rare, the most common cause of surface rust is super strong lemony dishwashing detergent combined with highly chlorinated municipal water. While most people will never encounter this problem with Caveman Cups products, if you do, it is best to change to a more gentle dishwashing detergent (we recommend Biokleen, Free and Clear Dishwashing Powder for dishwashers and Dr. Bronner’s, Sal’s Suds for sink cleaning). Any juice, food or other surface stains can be easily removed with a little “Bar Keepers Friend” non-abrasive cleaner.
