Suspect CMPI in EBG baby and accidentally ate cheese

Hi all, my breastfed baby is suspect has an intolerance to cmp because she gets really and upset tummy, trapped wind and rashes constantly if I have more than a tiny bit of milk (butter on toast or a couple of slices of cheese don't seem to have an effect but a glass of milk has her going stiff and in pain). It's been 5 months since I realised the correlation and have been careful since, it's become a mostly subconscious thing that I don't even think about any more having changed to oat milk and swapped a few other every day things. Today without even thinking I made myself a snack plate with brie, crackers and some meats. I didn't realise until I ate over half the triangle of brie and now I feel awful because she's probably going to have a day from hell tomorrow. I have the colic and widn medicine at the ready but is there anything else I can do? I've had it at night and there's going to be probably 8-10 hours between me eating it and her next feed but I just feel awful how can it have slipped my mind for a minute!? 😭
