We've been using Tommee Tippee for everything and have really liked their spill proof trainer cups for water but I'm running into a problem with milk. The milk is turning into froth when it's sucked through the spout of her spill proof drink cup. Am I putting it together wrong or is anyone else running into this problem with their sippy cups?
I'm in the process of giving her half formula and half WCM in a sippy before making the switch at 12 months.
Re: Sippy cup problems
According to the instructions, I have all of the parts put together properly. Everything is pushed through just fine. I'm going to try a different brand today.
I just switched around some parts from our old sippy cups and the new Tommee Tippee works just fine. Maybe it was a loose part, IDK. These damn things are so finicky! I might just skip to the straw version too @msspeedymarie. Thanks ladies!
