The secret to surviving the first 8 weeks is to think that things are really going to be tough and to recruit help for as much of the 8 weeks as possible.
In my case it was as follows:
Week 1 Extended stay at posh hospital
Week 2 Kevin
Week 3 My Sister flew in from US (loves kids; former nanny)
Weeks 4-5 My Parents flew in from Japan
Week 6 Kevin's Korean friend (not really experienced with kids but helped to load/unload dishwasher and carry things up&down the stairs)
Week 7 First week totally alone and was manageable
Week 8 Mother-in-law flew in from US
