Sippy cup

Fi

Anyone have a suggestion for a slow flow sippy cup? We are transitioning to whole milk and the sippys I have come out way too fast lol it just pours down her chin. She’s only been breastfed, never had to take a bottle so I think the flow is messing her up🤷‍♀️ she loves the milk and can hold the handles on the cup by herself, it just comes out too quick right now.

Pic is for fun😁
