Recommendations for a bottle that will help with gas/air intake?

Becky

Baby girl is 5 months now & we've been using the Dr. Browns bottles. She does pretty well with them but they're reaaaaaallly starting to be a pain in the ass to wash and clean because there is so many parts.

Any recommendations for a bottle that will help with gas/air intake that doesn't have 10 parts for 1 bottle?

Thank you!
