How long does it take to breastfeed?

Monica • Baby boy born 8/7/18. Baby girl born 3/9/16. Learning so much about life and love being their mama.
My daughter is 4 weeks old and I'm wondering how long a breastfeeding session took at that age for you? I feel like by the time she wakes up and I change and feed her it's always longer than 45min to an hour which is how long she's supposed to be awake in between sleeping.
