Adult Baby Review: ThinkBaby Stainless Steel Bottle

The ThinkBaby stainless steel bottle is aimed at chronological children, but it’s also perfect for adult babies and ageplay. I’ve had one for about 3 months now, so here’s my review of the ThinkBaby stainless steel bottle.

Teat: It’s not really a sippy cup (it was listed as a sippy cup before, but since I got mine they’ve actually renamed it as a bottle). As you can see from the photos of the mouthpiece, it’s got a squishy soft teat (like baby bottles) but it’s wider and flatter than a normal bottle teat, which means it’s aimed at people with teeth (it’s comparable to an adult pacifier). The teat is latex-free so anyone with a latex allergy can use it! It’s also BPA free, but I don’t really understand what that means. When you fill it with liquid, it behaves like a baby bottle too, and it doesn’t spill when you lie it on its side or turn it upside down. I use it when I want to lie down and drink something in bed because you can stop drinking to breathe without spilling anything.

Hot drinks: The main cup area is made of stainless steel. This basically means you can put warm drinks in it. HOWEVER, because it’s metal, the cup area will expand if you put a boiling hot drink in it, and the plastic of the screw top won’t expand, so be sure to allow really hot drinks to cool down enough before you put the screw top back on the bottle or it will spill (a lot) when you try to drink from it (this has happened to me a couple of times as I keep forgetting and making hot tea in it).

Capacity: It takes 290ml (10 fl oz) of liquid, which is the perfect size for an adult drink. I really like the fact that there are measurements engraved down the side of the bottle. If it was any bigger, I’d struggle to hold it up while I was drinking from it, so I think it’s the exact right size.

The measurements are engraved into the cup so you can choose how much to fill it.

Handles: The handles are kinda small (although I do have freakishly large, oddly manly hands, so it may work for most women) so men and any women with strangely big hands like mine will have a little trouble using the handles. They are removable however.

Price: It’s a lot more expensive than any of the other sippy cups I’ve seen, but since it’s metal there’s no chance I can accidentally melt it by putting something in it that’s the wrong temperature! As an adult baby bottle, though, it’s comparable with the other ones I’ve seen and it’s got the bonus of being latex free and not having a weirdly long teat.

Verdict: I love my sippy cup/bottle so much; I had a cheap plastic one from a local shop before I ordered the ThinkBaby stainless steel one from Amazon.com, and I love the ThinkBaby one SO MUCH more. It’s not available to buy outside the US as far as I know, but they do international shipping which is perfect for those of us who aren’t in America! Find it here on amazon.com

    1. Intriguing! Thanks for adding that — I looked all over UK Amazon before buying mine from the US and it wasn’t available when I bought mine, but it looks like they must have started selling it straight after! As a bit of an update, the lid has recently become super annoying because it’s a 50/50 chance as to whether it will leak or not each time I use it. I’ve found that if I fiddle around with it and keep drying the thread out with tissue it stops leaking eventually and will behave itself (fastening it tighter doesn’t help at all), but it’s such a faff that sometimes I just give up and take the lid off now. I’m not sure if mine got dropped or something, because it just suddenly started doing this a couple of weeks ago!!
