May i know when should i transition my lo to a straw cup and what are the benefits? I read sippy cup is not recommended. which straw cup is recommended?

Typically, babies can master the straw cups by the time they turn 15 months. My favourite straw cup is Tommee Tippee Explora straw cup. I generally love Tommee Tippee stuff because of their design and reliability. Here's an article that reviews and rates the best straw cups there are out there.
