Best bottles for self-feeding?

Since the recall of a bunch of plastic bottles earlier this year, my husband and I have exclusively been using the glass doc browns. They have been great but, now that she’s 9 months old, she seems a lot more interested in feeding herself.

The large glass doc browns are too heavy for her and so she gets bored of us feeding her and/or frustrated it’s too heavy. Ultimately, we end up with a very grumpy baby who is hungry but also uninterested in having us feed her.

Are there any bottles you’ve used that have been great for self-feeding?
