NumNumWeighted Straw Cup for Infant & Toddler 6-12 months - Expert Endorsed - 7oz Training Baby Cups w/Removable Handles - Easy to Use Self Feeding & Drinking Skills - Food-Grade Silicone (Green)

My baby really loves to drink water from this cup, it’s really easy to use, sometimes can have some minor leaks but anyway we love it!

Weighted straw is amazing. Toddler loves it.

Easy for my son to use but leaks significantly, unfortunately. I make sure that everything is sealed, etc. and it still leaks. I just make sure to only use water in this cup now for the leaking as my son does seem to like it!

Love this cup for my daughter. As soon as she learned to use a straw she has loved the independence of this light weight, easy to use cup! It is easy to clean and high quality. We have come back and bought another

This cup leaks everywhere and not just from the straw. It leaks from the rim when it is sitting upright with the lid screwed on. I have ensured all parts are secure, it still leaks. It’s also difficult to get the handles lined up so the straw is centered.I do like the design of the cup and it’s easy to clean. It’s easy for my baby to pick ip and drink from. Just wish it was not marketed to be spill proof!!

Our baby loves this cup! It is leak free, the perfect size, and we love that the weighted straw helps with no frustration of not getting liquid each time!

It's a good cup, my son learned to drink from a straw at 5 months from these cups and he's still using them at almost 2years. I love that they're perfect for his little hands and they do not easily leak. The downside is they are pricey and you can't just buy replacement parts.

Update: even with routine washing and using a straw brush, this little area is moldy and nothing I do can fix it. The mold got between two layers of plastic that couldn’t even be cleanedInitially, it was great but after taking it apart to wash it once and reassembling according to directions, it leaks through the straw now which it did not before
