I stopped biting my nails when pg with DS2, at about seven months pg they just became really hard and I didn't want to bite them anymore and I haven't restarted! I do notice that they break more easily now than when I was pg though. I use the Rimmel 60 sec stuff on my toenails, blue/silver sort of colour. I don't paint my fingernails, have tried but find it very difficult, still waiting for DH to treat me to a manicure after stopping biting my nails, oh and my mum promised me a manicure set if I stopped biting them (I was about 12 then so maybe she has forgotten )!
