I think there’s 2 types of Tum Tum sippy cups you can get, one is free flow which my little boy uses & water can come out when he tips it but because of the weighted straw it’s only ever a very small amount! I think there’s also one which isn’t a free flow though? x
@Niamh so there’s a silicone trainer cup design which is free flow but no weighted straw. That one if you shook upside down the lid would come off fairly easily! x
The tum tum weighted cups also leak if they go above or below certain temperatures (printed on the bottom of the cup). We have tum tum weighted cups and even with the slight leak now and again, we love them. My LB does like his milk warm though so I'm looking in to an alternative for this so we don't get more leaks x
If you shake it very hard it does leak ever so slightly but if you’re watching her with it then it won’t leak puddles if that makes sense 😊
