<human>: Can you provide a brief overview of the text?

So here's the deal: we had our first kid in October, so he's almost 4 months now. Our first baby sitter quit us because we complained to the agency when she called us away from school and work to pick him up when he spit up too much and then, on another occasion, cried too much. Soon after that, we got a new baby sitter. Today, she tells us that he cried for three hours straight today and that she'll see how it goes next week.

So we might lose her too. My kid doesn't cry like this at home so we're a little concerned. Am I being unreasonable when I say that baby sitters shouldn't quit parents because their baby cries? What can I do to curb his crying? We don't think it's colic. Seriously, he's awesome at home.
<bot>: my kid cries so much baby sitters keep quitting him. It's probably not colic. what do we do?
