My son is completely off the bottle and only uses the Munchkin 360 cups to drink both milk and water. I would love for him to be able to use a straw cup for water for when we're out instead of me having to bring a water bottle and fill up his 360. No matter what I do he doesn't see to grasp the concept of a straw, he just puts his lips on it or chews on it. When I try to get him to imitate sucking by watching me he blows instead. 🤦‍♀️ Any tips on "teaching" how to drink from a straw? I've been trying since 7 months and he's now 13 months!

I know it's not a big deal but it's kinda annoying haha!
