Hi girls and guy and bubs

i got josh weighed this morning and i am absolutely shattered and really annoyed angry and frustrated with Myself. He gained 80 grams this week. Thats not even now 1 kilo over birth weight he falls short of that by 130 grams. He is 8 weeks 5 days today.

What if i am harming him trying to only breast feed am i? I could be doing more harm than good.I am beyond shatterered!

Can u all tell me at what age did you bubs reach 1 kilo over birth weight?
