Having a 19 month old, I have some experience with sippy cups. I just bought this set yesterday at Target and I’m already in love! Tommee Tippee. They were on sale for $8 for 2 sippy cups.
Aidalyn drinks water in her cup, so it isn’t too messy when it leaks. It is however frustrating when her outfit is soaked. All of our sippy cups leak!!! Even though the boxes always say ‘leak proof.’ Aidalyn also loves making them leak & getting wet by shaking them upside down, charming to say the least. So we are really good testers for leaks.
