Re: Co-sleeping and diaper changes...
I usually have to change my LO inbetween boobs because he poops or pees and hates to sit in a dirty diaper. My nighttime stragegy is a little different from the PP's.... I jiggle the bed and wake up daddy and he changes all the nighttime diapers. It's the 'arrangement' we worked out. We changed the lamp on his side (which also has the changing table) to a low wattage light bulb and he uses that when he's changing the baby.
As for co-sleeping, well I said I would never do it but I am and I love it. We get a very good night's sleep and I guess I just feel in 'sync' with my baby. You will get over the being scared part very quickly and enjoy it. My LO is 6 weeks as well and I think we started this the 3rd night home from the hospital.
