Bottle Suggestions

Kit

4 month old, she’s using medela bottles right now & she’s drinking 5 ounces but the bottle doesn’t really go past 5 ounces & no signs of her moving up ounces yet but you know with babies it could happen anyday so I want to switch now to be prepared. She nor I are a fan of tomme tippee.. too much leakage. Give me suggestions or what you swear by please!!
