Best spill proof sippy cups?

BoyMom👣 • • Ryder 06.28.18 | Rylan 01.07.20 •

These are the cups my son currently uses and they are AWFUL. The Tommee Tippee say they’re leak and spill proof and that’s a lie! I’ve seen so many different things online about what’s the “best” sippy cup so I figured I’d ask real moms instead of continuing to google and get nowhere. Any recommendations?
