Pros: 

• No spill

• Relatively easy for holding

• Good straw learning 

Cons:

• A little challenging to clean (for germaphobes like me)  

• Awkward storage in diaper bag 

Our experience: My family and I love these cups. Though it took a week or two for my baby to figure out how to drink out of a straw, he has been using this straw cup ever since. The cup is easy for baby to hold and doesn't spill as he is drinking out of it or when the cup is dropped. To me, the straw is more challenging to clean than other straws, and because of that, I don't think I'd use Munchkin Straw Cups for anything other than water. The handles also make it a little awkward to store on the side of a diaper bag. 

Pros:

• Can help baby learn concept of straws

• Great cleaning tools included

Cons:

• Baby outgrows very quickly 

• Lid flap can be distracting for baby 

Our experience: Our baby had a hard time learning to drink from a straw, but the Honeybear Squeezable Strawcup helped him to understand the concept of a straw rather quickly. I was impressed with the cleaning tools that came with the bottle, and I have been using those cleaning tools on other bottles. Once your baby masters the straw, they no longer really need this cup. Our baby also really liked playing with the lid flap. 

Pros

• Could help with transition to cup holding for older babies and toddlers 

• Ounces marked on cup 

Cons

• Water leaks out of lid when tipped 

Our experience: Though the Olababy cup isn't really ideal for a baby who is just starting to learn how to work with cups and straws, it is a good, easy-to-hold cup for more experienced drinkers. The ounces marked on the side of the cup also come in handy when determining how much liquid a baby is actually consuming. The biggest drawback is that the cup easily leaks when the lid is tipped. 

Pros

• Good practice for transitioning to cup holding & no straw 

• Less spillage (compared to bigger cups)

• Easy for baby to hold

Cons:

• Messy 

• Can't fill up directly with fridge water 

Our experience: The ez pz Mini Cup is very easy for younger babies to learn to hold. Because the cup is so small, there is less spillage. Though I wouldn't recommend this at a restaurant or outing, it is good practice for dinner table meals when parents have the patience to refill spilled water (which will inevitably happen as babies learn to drink from a cup instead of a straw). One unforeseen drawback was that the cup is so small that I cannot directly fill it up from the fridge. The cup is too shallow, so the water splashes out. Instead, I have to fill another cup and then transfer that water to this cup.
