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.

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 Amazon.com. 
 How do I clean and care for my Cub Cups?
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.
