Baby help🙈😢

Cr

Hi everyone

So I had my baby girl on 26 May 2019 and she was a healthy 3.05kg and she was 50cm long.

We have been home for just under a week now and she is starting to make me worry a bit

I am breast feeding and she gets more than enough milk for her size and I can even see that she picked up weight by her cheeks but when I'm done feeding, burping and changing her she breathes very fast....like extremely fast and she does this thing in her sleep where it sounds like she stops breathing and then suddenly gulps for air

What does this mean?

What can I do?

I just want her to be safe and healthy
