babe i would just lay back and enjoy the rest of your pregnancy...
believe me there is nothing relaxing or joyous about nesting i couldnt stop nesting from so early on that i actually nearly went too early..
as for names thats something you can decide whenever you think you have found the perfect name my SIL didnt name her daughter till she was 9 weeks old... we used to just call her bubba lol
i think your ds will adapt alot easier then anyone will expect my son has extreme behaviour problems and he was over excited when she came home he asked if i could go buy another baby and put it in my tummy lol
enjoy your pregnancy babe and remember you still have 8 weeks thats along time to go (not really) but thats how it will feel soon...
