Anyone else have a grumpy baby?

br

Our baby girl is 3 months old. She literally is always upset, always crying, always fussy. All her needs are met, we play, we feed, we sleep etc. It's not her formula, it's not constipation, it's literally for *no reason*. The only thing that SOMETIMES gets her to stop is to make her take a nap (which she will do but fights it and always has) or watch Hey Bear on YouTube 😅 is it just us? Does she hate life that much? Like why is she always cranky and grumpy nonstop? The doctor chalked it up to colic in the early weeks but she's now over 3 months old and she's the exact same...... it's not a sleep or nap issue IMO so she's literally crying just because?
