The First Years My First Open Cup — 2 Cups in 1 — Open Baby Cup with Removable Spill Control Insert — Training Cups for Transition to Toddler Cups — Ages 12 Months and Up — 2 Count

This is an ingenious design. I have spent way too much money on cups for babies that haven’t worked out. So far this is the clear winner and I’ll tell you why. It’s because it’s not overly complicated.I’ve purchased completely closed off designs that the child has to purse their lips or bite to get the liquid to come out but it’s easy to complicated for my child and my child is very, very, smart.Yes, I agree those closed off types do contain the liquid well and are good for unsupervised water but my daughter doesn’t understand that she has to completely lift the glass upside down with her head tilted all the way back to finish the drink. I stopped using that style because My daughter was only drinking half of whatever I put in because she’d get to a point thinking it was “all done”.It was also not realistic in its design. Having to lift it up all the way becomes problematic when I have to give a real cup in public or if her “contained” glass is dirty.Now, this style isn’t perfect either but it’s pretty darn close. It of course has to be used in a supervised capacity. It is an open cup so it’s perfect to use at meal times when sitting in a contained high chair.I purchased a washable dog whelping blanket also called a doggy pee pad blanket for about $50 and have it placed under my high chair so it can catch all thrown food and spilled drinks. What I like most about this glass is that it’s perfectly sized for my daughter. If she lifts it too high she’s not doused with an entire glass. It allows her to learn how to accurately judge how fast it comes. (The closed styles don’t let it flow like a natural open glass)I also appreciate that when it does get dropped (accidentally or not) it only allows a small amount to escape or splash.I also feel that the cup in a cup is such a smart design for cleaning purposes too. It screws in easy and isn’t over complicated. So when my daughter stuffs her sandwich in it to experiment I can clean everything without nasty crevices and gunky corners to try and figure out how to clean.For me this is a great Tool. I use those 360 straw cups when I am not training then switch to these at meal times when I can adequately supervise and support. I love this product and highly recommend it.

Disappointed. The concept is great but it doesn’t hold much. You are constantly taking it apart and refilling it which causes and angry thirsty baby! It also doesn’t flow back in, once the cup is turned sideways it pours out

I love that these are so simple yet so beneficial. My child went from being breast fed to using a big kid cup with very little transition period thanks to these cups! Simply fill the small green inserts, carefully insert them into their cups, and watch the magic happen! You dont have a ton of free standing liquid at any given time which helps reduce spills! I absolutely recommend these for all kids!

My daughter (one and a half year old) always wants to steal my glass cups, so I was in the market for something more her size and speed. I don't know what exactly I was expecting, but these are just okay. They are easy to use and clean. The flow definitely was smaller which really helped her learn to hold the cup herself without getting drenched. But despite those positives, it really doesn't hold a lot of water which made it slightly useless. Constantly having to refill it defeated the purpose a bit and did cause some water to get everywhere since already wet. My daughter also had an obsession with trying to get the inserts out which completely defeats the purpose. I don't want to knock the product too much since it did as described, but I don't think it really served enough of a purpose for me. I have since switched to just using the cup without the inserts.

We introduced this when my baby was 9 months old and by 10 months he was able to drink pretty much independently from the cup. It offers real open cup drinking movements that sippy and 360 cups can't offer so this is much better from a developmental standpoint

I absolutely love the idea of this cup. But it does not function like the pictures and videos describe. At the right angle and position the flow is a small trickle but it is a constant flow. If you put it down and leave it then pick it up for another drink the liquid has leaked out of the insert and just fills like a regular cup.In my opinion there are better cup trainers on the market

I've tried multiple kinds of adaptive cups for children new to using an open cup and this one is easy to use and effective. Children cannot easily remove the insert to pour out contents and it only holds a small amount so even shaking or turning it over only allows a tiny amount of liquid to spill. Easy to refill and assemble for use.

These do not work and you can barely place any liquid in them to “work.”
