Sounds lovely to be in NYC, Elodie!
Bigfam I've suffered with cold sores my whole life. Theyn tend to pop up epscially in pregnancy as immune defence is low. Try to avoid kissing and touching your child's lip and don't share food, utensils, cups or towels etc. Treat them with Zovir cream, and make sure the child gets more rest than usual as they tend to be a sign of lowered immune defence, as you alweays have the virus in your body and then they crop up when you're weak. Also, I found (and research supports this) that nuts and soy products provoke them, and that meat and leafy greens help. Never heard they should be dangerous, but then I had them since childhood so when I ahd them in pregnancy it was not the first time. Also - and this is just my theory - but I think some people are just more prone to them than others. My mum, sis and I all have them, and my dad never had them, and I'm sure that through all the years of living with all three of us, he's been plenty exposed to the virus! So maybe you already have the virus in your body but it just doesn't break out for you.
Also finding it so hard to sleep, wake up to pee all the time and find DH presence in bed really annoying! I normally love cuddling up to him, but for some (prob hormone related reason) I know find that he takes up too much space and spend the entire night pushing the poor man to the edge of the bed and complaining I don't have space enough 
Also, anyone finding it really ahrd to focus on work?`I was the same last time, around this time I just sort of stop caring, it's so hard to have any motivation! I also become crazily honest, my boss just asked if I fancied going to some event next week in the eve, and I straight out told him that that particualr event was mainly a networking thing and din't entail anything of substance realted to my job, so I didn't want to prioritise it given I am going on mat leave soon! after he left I felt I'd been way too honest and done a blunder...
