I second the nuby brand one! Woolies sell them! DD really took to the softer topped one. She found tommee tippee ones and heinz hard to get enough liquid out to satisfy her. I had a go and I was shocked to how hard they seemed to be to get the contents out. Since the sippy cups I have bought all of their products. Bonus is they are all BPA free and dishwasher (top rack) safe!
