It definately does improve in the second trimester.. well i found it did for me, but not until just after the 14 week mark. As i said before, i think a big factor is feeling so exhausted and feeling the need to sleep all the time. I think it would be harder for you possibly this time around because you have little James to keep you on your toes at home too! Maybe you can explain to Chris how you are feeling this time, and he can take care of James a little more until you get to that stage where you are feeling perky again, and just get some extra rest until then - i promise it will help, i went through the same thing
