Unhappy baby

Does anyone have a generally unhappy baby? I’m just curious to see if I’m not alone! My LO is 6 months and she just screams most of the day. I do get a few smiles and giggles here and there but most of the time it’s a lot of fussing. She’s been like this from day 1. I haven’t eaten dinner without holding a screaming baby in 6 months (my husband helps my two year old eat during dinner which is another battle so neither of us have a relaxing meal), she catnaps (5-30 minute naps all day long) and wakes up screaming. There’s just not a lot that’s pleasant about her. I’m a SAHM with a 2 year old and this LO so I’m used to the screaming at this point, I just feel bad that she’s so miserable. I’m sure there’s nothing to be done except wait if out, just wondering if anyone else is in the same boat 😕.
