Yellow Snot nappies and no weight gain for 2 weeks - Should I be worried?

[splodge2001]

DD is 17 wks. For the last 2 weeks she's produced yellow snot-like stools - smell normal just very liquid. Before it had those seedy bits. She's going about once per day and seems happy.....BUT she has only gained 80grms in the time shes been producing these nappies.

Before the snotty nappy she was gaining around 160g per week.

We also have a question mark over her health in that she has slightly high level if ALT -which is being checked again on Tues

I guess im really worried that the snot nappy is tied in with the ALT

does anyone know what might be causing it?

sorry to be thick, but what is ALT?

My DS has nappies like these too. HV Said it was nothing to worry about, probably just a cold and they've been swallowing the snot

Has she had a cold?

I think it is ok, but if they continue for more than 10 days and you find some blood in it, it may be a food intolerance (either to something you are eating if you are breast feeding, or to cows milk if you are FF)

ALT is a liver enzyme - could mean liver damage

has sneezed a little, not really snotty. its been going on for a while, longer than the average cold.

sorry i meant 2 say she is EBF - no blood. i havent changed diet. could an intolerence just sponteously occur?
