This sounds like my DD2...
She's 4 months now and never stopped crying, I could never put her down, it was absolutely ruining my life and especially my DD1's life..
I asked for advice on here, took her to the doctor many times.
She had infacol, gripe water, different formulas, different bottles.
We bought a swing, a mamaroo, different play nests, different bouncy chairs, dream Sheep, white noise machine, star projector.... Nothing worked.
She was the prescribed gaviscon, then ranitidine, and now dairy free formula.
We took her to cranial osteopathy, baby massage and several baby classes.
She might be a little bit better, it's hard to say, she still cries a lot but she also has new periods of happiness that weren't there before. She is much more smiley, but it could be her age rather than anything we are doing. Getting into a routine has undoubtedly helped.
But she is definitely a 'bad baby'. I'm just trying to live by the thought that she will grow out of this, and that sometimes I can hand her off to my DH or my mum and escape for a bit.
Don't they say on here, this too shall pass?
