Baby weights at 6 months

I always thought I didn’t have enough supply bc of negative comments from family that I didn’t eat enough after c section complications but thankfully I pushed through. My EBF is 20 lbs. the doctor said it isn’t too much bc she’s tall. But now the same family member that said I wouldn’t last 1 month feeding now says I’m over feeding her. She feeds one breast at a time every 2 hours. She doesnt use a pacifier. And co sleeps. She finally sleeps 4-5 hrs straight without feeding. I know they say you can’t overfeed a breastfeed baby but is this weight gain normal? She was 7.4 lbs at birth

What’s your babies weight now? Are they ebf or formula feed?

Thanks.
