Gassy baby/Dr.Browns bottles

So my baby used to cry for 2-3 hours a night for several nights a week until I changed her bottle from Dr.Browns to Playtex drop ins. I kept thinking maybe it was my breast milk causing her discomfort.. Something I was eating. Which is a sucky feeling cuz I had no idea what it could be. Milk allergy came to mind but my doctor said she would have other symptoms and bloody poo so it probably wasn't that.

It has been one week since using playtex drop ins and she has slept peacefully and no crying episodes at night anymore. She slept 4 hours last night before waking to eat. She is 6 weeks on Friday. I hope it continues. Just wanted to share in case anyone has those bottles and is experiencing the same thing. I know what works for one baby doesn't always work for all babies.

I used playtex with my other kiddos in the past and tried Dr.Browns with one of my kids before and she didn't do well with them either so not sure why I tried Dr.Browns again. I imagine if baby was older and system was more mature Dr.Browns would be fine.
