EBF - weight gain issues

Ra

Below I have attached her weight chart because my CaHFS nurse is concerned with her weight gain and so am I now.

So I have started to use this app to track all her feeds etc as of yesterday to get a better idea of what might be happening.

I have been expressing with bottle top up feeds for the last week now, prior to that it was solely the boob. I have also been prescribed something to increase my supply...

When she was a new born she was diagnosed with Hip Dysplasia and had that for 9 weeks then it was of part time then full time over the last month where she has become much more physically active, kicking, rolling, wriggling along with a growth spurt where she viably got longer.

In the last 24hours she has had 18 feeds from both the boob and bottle.

Is there anything else I can do or try? Or is this really common ?

Thank you in advance
