Does anyone use the Kiinde system? Does it really help with colic? Right now we use Tommee Tippee anti colic, but I keep getting bags and Kiinde bottles with my pump accessory restock so I'm wondering if it might be less of a hassle to just use those. We only give little man one bottle a day so I'm wondering if it will even make a difference. It would be so convenient compared to washing all the tommee tippee parts.
