Expressing emotions around baby

Does anyone ever express emotions around their baby? My baby is three weeks old and sometimes I get really frustrated or annoyed because of something, and she's awake to witness it. Most of the time I am very calm and I keep a happy and positive tone around her, but sometimes I can't help but get frustrated in the moment.

Hopefully this doesn't affect her in any way. Just curious if any other mamas express not-so-positive emotions around baby sometimes.
