We have an au pair at the moment to look after DD for a few hours a day after nursery and to help with the housework. It works very well.
I'm expecting DC2 in the spring, and I'd always assumed that, as I'd be on maternity leave, there'd be absolutely no point having an AP, and that having somebody else around the house would be annoying if I'm home full time. I'd keep DD going to nursery 3 or 4 mornings a week for continuity, because she loves it and I wouldn't want to stop it just to try and get her used to it again when I go back to work. So I'd have 3 or 4 mornings with just DC2, and the rest of the week with both (plus DH would be around at weekends of course).
Those of you with experience of having a toddler and a new baby, would you have appreciated an extra pair of hands, or would you prefer to go it alone? I can't help but think that its a bit of a cop out for me to pay for help with my own two children when I'm on leave anyway. AIBU?
