Slow or medium flow nipple

Taylor

My daughter is a little over 3 months.. she uses a slow flow nipple.. it seems to take her longer than usual to finish a bottle, she falls asleep not finishing it and then is hungry soon after. I tried a medium flow, she eats a lot faster and seems to do better but I still feel like it’s too fast. Some comes out of her mouth, I’m assuming it would until she gets used to it coming out faster?
