Bottle feeding

I am 9 days pp and managed to get 2oz from the haakaa today while I breastfed. I have a nap either side of the night shift and was thinking we could extend my sleep in the morning if my partner bottle feeds this.

Any drawbacks to my plan here? Learning every day so I’m open to thoughts :)

Will using the haakaa effect supply? Could a bottle confuse things this early?
