Every surgery is different, but mine went really well. I would arrange for help with the kids, you will be exhausted the first week and then gradually less so. I had a large (3.5cm) tumor removed translab. Had almost no balance issues post op as the vestibular function was already pretty well compromised. The quicker you are up and moving around, the quicker the balance restores. It was recommended to me- short "exercise" sessions followed by sleep and then do it again sooner rather than later- seemed to work for me. I'm now almost 6 weeks post op. I've been back to work for a month- although the first couple of weeks were part time. I started driving again after 2 weeks, too. But I was still taking frequent naps and limiting my kid time (I have a 2 1/2 yr old boy and an 8 month old girl at home). Noisy, busy environments tended to make me tire quickly..... Still waiting for my facial function to return to normal- seems to improve every day and the doctor's are confident it will all return in time.
Anyway, I recommend finding full time baby help for the first week or two and then adjust as needed. You will be exhausted and in need of lot's of quiet time.
