My son uses a hydroflask when drinking water. For milk we use the ZAK straw cups. At daycare, he drinks out of an open cup.
I got my son an owala cause he always likes to drink from mine and he does really good with it. But it definitely takes practice with them I think
We are ZAK people for sure! Least spilling, dribbling of anything we’ve used with our babe!
Some daycare or preschools doesn't allow straw cups so a flip up mouth piece works. You can get one with a hard mouth area so he doesn't bite
