Hugs Hun, I know you've been feeling very anxious about taking the meds. Bear in mind it may just be a blip and nothing to do with the meds, it's easy to read too much into a normal bit of feed variation
both mine have gone through periods of feeling less hungry and me feeling fuller and supply hasn't been an issue if we just kept on going and feeding when they were hungry
did I read that LO was teething too? Going off feeds can be very normal if that's the case xx
