This has come up before. Working from home doesn't often mean that you don't need childcare.
What did you do before?
I work for a large IT services organisation and all the field sales, project managers and support staff work from home. Over 10,000 in the UK. I am field sales, when I am not in front of my customers I work from home. It's great as I get to drop off baby at nursery later if I am having a quiet day and on a nanny day I get to see a lot of baby by popping to see what they are up to between calls and loo breaks etc
