baby's weight gain

C.

My baby girl's birth weight was 2990 grams, dropped to 2840 g.

At 1 month - 4 kg.

At 2 months - 4.8 kg.

At 3 months - 5.7 kg.

6 days until she's 4 months - 5.8 kg

We're gonna see a doctor next week, but we have already talked to him on the phone and he said everything is fine.

I'm not so sure about it.

What do you think?

She is exclusively breastfed.

She looks healthy and is happy and definitely sweet.

Please help me. My husband keeps telling me that I'm overreacting and s.hit...
