LO somehow always gets a lot of air when feeding. I've tried so many different bottles: tomee tippee (sensitive tummy ones), dr browns, the medela ones that came with the pump when I was pumping, avent. Currently using playtex drop ins. Somehow, even if I make it so there aren't bubbles in the bottle, it's like LO PUTS the air bubbles in there. I remove it from here mouth and bubbles seem to be going INTO the nipple. (So confused!)

My question is, when I try to burp her, she cries. Starts with a fuss and develops into a full cry. Do I keep trying to burp her? She will stop if I give her back the bottle, but that only makes the gas/bubble problem worse...
