The smell

Miranda
So for the last few days my son hasn't been eating well (-3oz) and I just noticed a smell coming from my sink and was thinking​ it could have something to do with why he's not eating properly but it also seems as if he's getting thrush again though the first time didn't affect his eating. It's really starting to worry me because we just got back to nursing well after his first two teeth came in. In all honesty it could be all of these but I really hope it's just the smell because I can't take another 2 month long nursing strike.
