Baby fussy and pulling away at breast

Savannah

My baby is 5 weeks and the past week she has been frustrated when feeding on and off during the day. She will suck for a minute at most and pull off and cry. I am BF and pumping and the only thing that will satisfy her is giving her a bottle of my milk. She’s never fussy with a bottle. We met with a lactation consultant and of course she ate beautifully! The consultant said maybe she has colic but I think it’s more to do with the flow of the bottle. It’s very frustrating for both me and baby and if anyone else has any experience or advice/suggestions I would really appreciate it!
