My son was doing this as well. We started giving him a hard spout sippy cup and a bottle with the sippy cup nipple. He transitioned on his own and for drinking out of a straw, I would recommend the honey bear straw cup.
Same, we had a sippy cup that worked for like 2 weeks and suddenly he started asking for his “baby ba ba” (bottle) so it’s rough! 😭 I think we just have to go cold turkey soon and throw them all away
We switched to the nuk sippy cup for milk. She will only drink milk out of the sippy cup. Everything else she uses a straw cup
Same here so no advices but following
