But the whole point is you don't need to research. Your baby is crying and that bothers you? Pick them up! Feed them! Surely we don't need experts to tell us that. Your instincts tell you that. If your instincts are off and don't tell you that, then you wont be bothered by the crying either, which is clearly not happening if you're one of the people asking what's up.
No we don't need experts to tell us that.. But when your baby cries, you pick it up, it still cries.. You don't pick it up it cries.. But when the advice of a stranger who is also swearing at you telling you how dumb you are, or the advice of a well meaning family member conflicts.. I think the advice of the family member will win..
