Working from home is a double edged sword.
I think you just need to make boundaries on your time.
Don't let your employer call at any time. ANd make sure that people at home know its your "work" time.
I think overall you should give it a go but just try and keep work in a box if you know what i mean. Mayeb have a "work" place and don't let it spread, also if your DP is around at the time your working could they be responsible for any child rearing needs?
Sounds gerat though, Give it a go!
