Bottle feeding breast milk

My baby is 5 1/2 weeks and we just started introducing a bottle to her with pumped breast milk as breastfeeding has been well established. Im planning for my husband to take over one of her feedings a day or if I go out for a bit. I’m just not sure how much I should be giving her?? She weighed 13 lb 12 oz at her 4 week appt. Tonight we gave her 4 oz (the max mine hold is 5oz) and she guzzled it back pretty quickly. Only an hour after she was pretty fussy and seemed hungry, lots of mouth movements and sucking on her hand. Although lately I don’t know if this is just because she is just finding her hands as she won’t take a pacifier. How much do you feed your babies?
