HELP! ftm needing breastfeeding input n advice please!

Hi ladies!

4 days pp here and my little one is a trooper when it comes to breastfeeding. she latches perfectly & eats a great amount. Sometimes she’s on my boob for 40minutes!! She was cluster feeding at the hospital so all my milk came in by 2 days pp and I got engorged QUICK, so I got a pump 😅😋

I have inverted nipples and have been exclusively breastfeeding her during the day but at night time my breasts are really sore from the day feedings so I was wondering if I could give her bottles of breast milk for night time feedings? Will it mess up my growing supply???

I usually breastfeed bare during the day, use a nipple shield whenever they start to hurt, then give her 2oz bottles at night and pump throughout the night when I wake up to feed her.

(I know a lot of people say to wait 3 weeks or so to introduce a bottle but based off of how she’s reacted I don’t think nipple confusion will be a problem will my girl)
