Tiggy, I am working PT at the moment and will go back to work again after Little One is born, but that is only because I have a DH who is prepared to (essentially) be our children's main carer. But still my career is "suffering" because I am not there full time, but that is ok because I think of the song "Turn, Turn, Turn" (or the passge from the Bible, if you are religious) - for every thing there is a season and a time unto heaven. There is a time to work and one to be home, and what you do now doesn't need to dictate the next 20 years of your life. Do what feels right for you and your family
