Herbs and spices are fine, O has had mixed herbs, cinnamon, a little chilli powder and some oregano in his foods one way or another. Also black pepper.
YW No, not weird at all. I feel like this because DP is around so much. It's great that O is bonding with him. But I feel a mix of relief for a break, but jealous that he might be happy with someone else. And that mummy just isn't as good as others :(
I always do the bedtime routine, so that I know, no matter what, I will get that one on one time with him every day. Even if the rest of the day has been busy and I feel like I've barely had any proper time with him. And I take O out as much as I can manage. So that I feel we get time alone. I leave DP at home to do the cleaning!!! 
I admit to being very grateful now that O is not going to a CM. But he will be with MIL. I was happy with this until some recent events, now I am not so thrilled with it. But I don't have much choice. I hated DS1 coming home smelling of someone/somewhere else. It really made my ragey hormones, erm, rage. I had to strip him off and bath him.
It's the same when he comes back from his dads. Although now days, he doesn't get close enough to smell. So it's okay!
Sorry, I've got no answers! Only more questions really!
