I ate half a cookie - how long for milk proteins to clear from her system?

[C&B&E]

Ugh.  I am so silly for doing it - but we were baking cookies on Sunday and I ate a bit of mixture and then a bit more when they were cooked  .  DD is BF and I haven't had any dairy/hidden dairy for 5 months.  She was uncomfortable yesterday and today she pooed while I was changing her and there was a bit of liquid/mucous strings coming out of her bottom  .  I obviously feel terrible, and am wondering how long it will take for this little bit of milk proteins to clear from her system??

thanks

I used to find if I accidently had anything it was a few nightmare days and then back to normal more or less and my dd was very sensitive. It is so hard to keep the diet clean isn't it? Make sure you have some legal treats for over Xmas, I remember that being the worst time for me
