Grosmimi Replacement Straw Kit (4 Straw Nipples-Stage 2)

These are great to help baby get the last bit of milk or water out of the bottle without having to tilt it. However, I've noticed milk tends to rise up and out of the straw if there is a temperature difference between the liquid inside the bottle and air temperature. Pressure builds up and if you're not paying attention, it overflows. What helps is to unscrew, lift straw out to release the liquid back down and close again. Simple but annoying. At first I thought it was a defect in the design of the weighted straw, but found this to be the case even with the standard straw that comes with the Grosmimi bottle. In fact, it happens with the other brands too so not specific to this brand.

My toddler had chewed holes in the original straws. These are perfect replacements for the grosmimi straw cups. Durable, easy to wash, and fit perfectly.

Good

Stage 2 Silicone straws that are durable yet super soft for baby’s gums and teeth. This is the perfect replacement compatible with the 10 oz and 6 oz Grosmimi cups. Love the fact they are spillproof. You must cut the straw in order to fit the 6 oz cup but is very simple with the included measurement guidelines. Cleaning is easy with the included brush.

Great straw for six months and up, very easy to clean. They are on the softer side, so if your child is a chewer they will be able to chew through the straw after a while. Other than that, it worked great for us and they do not leak.
