Grosmimi Replacement Straw Kit (2 Weighted Kits)

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.

Good

Works great! My toddler learned to use straws by using grosmimi straw. They are easy to drink from (other popular brands are so difficult to suck from) and are soft. The stage 2 straws are more durable than the stage 1 and perform perfectly. I use them with the Avent Anti-Colic 11oz bottles and the straws fit perfectly in the collar. I need larger bottle for my toddler so the Avent 11oz is a good size. They also fit the mam bottles perfectly. During teething the straw does rip eventually but without teething it lasts long. Highly recommend

These Grosmimi replacement straws fit our existing cups perfectly. Installation was simple, and the flow feels just right for my child — not too fast and not too slow. I also appreciate that the material is soft but durable, so it’s gentle on the teeth and doesn’t wear out quickly. Cleaning is easy, especially with a small brush, and there’s no lingering smell after washing. If you already use Grosmimi cups, these replacements are a must-have to keep everything fresh and hygienic. Highly recommend stocking an extra set!
