Gassy baby has problems with bottle

Cheri

Hi everyone. My daughter is 6 weeks old and I both breastfeed and pump milk for her so she can be left with family while I run errands. She’s been gassy recently and it seems to be worse after giving her a bottle of breast milk. I know she will swallow more air using a bottle, so I was wondering if any of you out there recommend a brand of baby bottle that is best for gassy babies and/or strategies for dealing with feedings? Thank you so much!
