Question: Whats the diffenence between the 12 oz and 12 ounces? its the same isn't it?
Document: I tried practically every cup on the market for my daughter but this is by far the best! No leaks!! She started using them at about 12 months, I was nervous because the spout is so hard, but she never had a problem. We did have one break, it was dropped on cement while full. I contacted the company and they sent me a replacement in two days. This is the only sippy cup to buy!
Ah, the irony: When my boys were 12 months old, we worked hard to get them used to holding a straw sippy cup (down) rather than how they held a bottle (tilting it up). They've used straw sippies exclusively for the past 6 months ... so when we gave them these Nalgene bottles at 18 months, they could not for the life of them figure out how to drink out of them!
We have had all 12 for at least 2 years and some of them longer since we purchased our first one when our eldest son was only 20 months old. Sooo at least 3 years of use for the same sippy cup is impressive. We have not had to purchase replacement valves as of yet.My only wish was that they made this with a stainless steel canister. They are BPA free which is great, but stainless would be even better.
we love this water bottle! our daughter drinks more water when it's in this bottle. plus, it doesn't leak!
we have 4 of them at home and use 2 daily. Will never go back to using the baby name brands again!
this was a gift
this is a great sippy cup for toddlers. my son loves it. and, i like that it's safe for him.
this is a decent bottle. I bought it for my 2 year old as a milk sippy cup for before bedtime. It is pretty difficult to suck the water/milk through. It is getting easier as it gets used more. We moved onto different sippies, though. Love the Camelbak kids sippy!
this baby cup is legit. it's not cheap or thin like the other ones sold at the store. This is more like his mother's hard shell BPA free water container from whole foods. Solid purchase kiddos.
these is a beautiful BPA-free water bottle..It is perfect gift to a baby shower..is very useful specially when you have a car seat.
