Since I purchased the Philips Avent Isis breast pump, I also decided to go with the Avent bottles. While I love how easy they are to use (and convenient, considering the pump is the same brand), C seems to be swallowing a lot of air. It breaks my heart when he gets his “gas cry” after eating. I want to make it go away! I read about Tommee Tippee bottles, which are supposedly great for breastfeeding and gassy babies. I ordered them through Amazon Prime and they should be here on Wednesday – I wish they’d get here even sooner!
