When I booked the scan for mine, I wasn't sure but by the time the scan date came, I knew but decided to carry on just to confirm my suspicion.
All I wanted to know was she in whelp, for me there is no point in having a 2nd scan.
The children(& yourselves) must realise that the bitch could have a temperament change, particularly once the pups are born...she will get very protective, which you as a mum should understand. Mum & pups should have time alone(away from the children) to bond & sleep/suckle.
