I had my first child at age 32, by that time I'd worked for 15 or so years. I then stayed at home until my youngest went into school full time then I went back out to work mornings, I was lucky I worked for my husband's business so I could work around my children and did bits and pieces of work from home when I could fit it in, in the school holidays. I never felt like a parasite ever!
I'm just wondering how the logistics of taking a very new baby into the office actually works, only from my memories the palaver of feeding, winding, changing and settling could take several hours, after all it's not something one can hurry along, as all the professional advice was "go at the pace of the baby" and lets face it they could fall asleep mid feed. Repeat at intervals throughout the day, just pondering how any work would get done, not to mention how colleagues would feel about the work place being turned into a nursery..........just wondering ?
