Concerned about 6week old weight gain

As the doctor says, as long as she follows her curve then she’s fine. Sounds like you’re doing a great job x

My baby is now 7 months. I obsessed over her weight for the first 6 months. It consumed me for a very long time. I compared her to the bigger babies constantly. I’ve now come to realise, some babies are just smaller and don’t gain as much as others. As long as she’s following her centile line, your baby is fine. Weigh her weekly for the next month if you’re worried. If your baby is gaining slowly, following their line, having 6+ wet nappies daily, seems happy and meeting milestones, please do not worry.

Weight gain isn’t linear. My boy dropped steadily from 40th centile at birth to 6th centile in the first 2 months (he never lost weight just gained very slowly) the health visitors and doctors weren’t concerned at all but I found it stressful. However he then had a growth spurt around 3 months and then slowly climbed back up the centile eventually sitting around the 30th. As long as baby is having wet nappies and isn’t losing weight I wouldn’t be too concerned.

If you’re having pain latching I’d investigate this as slow weight gain and pain can be indicative of tongue tie.

How often is she pooing? x

Do not end breastfeeding 🙏
Agree w , lip or tongue tie could explain the pain latching.
But you're doing a great job, trying to wean off formula, too, it would be a shame to stop breastfeeding just bc you're stressing. Pump whenever you give formula and soon you'll be able to wean off.
Count diapers, does she have enough diapers ? Is she overall happy?
I went through similar, dm me if you want more details or w any questions, I'll be happy to help
