## Description

desertcart.com : Grosmimi Replacements (Weighted kit 2-Counts) : Health & Household

Review: Good, but be mindful of "pressure" causing milk to rise up the straw and overflow - 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.
Review: Usable in munchkin cups - I use these in my munchkin straw cup. It fits perfectly, and is weighted so my daughter can drink from the cup at all angles. They come with a brush, so getting them clean is fairly easy, but they do take a while to dry. I still recommend them
