Previous df/sf dd havung symptoms again?

[chipstick2810]

My daughter was df/sf from 5 months until 13 months when she outgrew her allergies and has been fine ever since. She is now 20 months. She has just gotten over a bad cough/cold and the last few nights she will not sleep and is just screaming the entire time she is awake.

She seems to have a lot of wind and refused her cows milk (which she loves) for a couple of days but started drinking again yesterday.

I don't know if I'm reading too much into this. Has anyone experienced a "relapse" months later following an illness? When I say she isn't sleeping at night, I don't mean in the usual sense, she is beside herself screaming for hours on end as she did when she was tiny and gave her milk before realising her allergy.

Does anyone have any experience of this? Many thanks
