Sippy cups

Ke

Is anyone else’s LO having a hard time figuring out how to drink out of a sippy cup? I have tried a soft spout trainer cup, a 360 cup, a weighted straw cup, and a hard spout cup with my daughter and she hasn’t figured out how to drink from any of them. She puts it in/to her mouth and just chews on it. I have tried with water and with breastmilk.
