Ally i'm in exactly the same position - not so much about sharing the time as i already look after my neice 4 days a wk and we manage really well - but mostly concerned of the lack of attention throughout the preg. i'm soooo worried i'll be as sick as i was with dd - almost 5 months of really bad m/s...could hardly get out of bed some days. But i figure i'll eventually have to bite the bullet and go down that track again someday so i may as well do it now when i'm feeling really on top of things and think it's the right time to make dd a little sibling
