Personally no.. We did try it with Ds 2 at the end of last year but he was just so upset and so was I.. and he only went for 4 hours for 3 weeks in a row..

I wanted him to get used to being separate from us as he has school next year and is rarely looked after by anyone but myself or DH..

I have heard one day simply isn't enough but I wasn't emotionally able to do it anymore then that...

I think it is always a good idea to give it a go.. plus you work weekends and with baby 2 on the way you deserve some time to yiurself as well kwim?

I think give it a go see how she does..
