At 8 weeks, your baby runs completely on instinct. Most pediatricians and parenting experts agree that you can not spoil a child enough within the first 3 months of life.
It's also the period during which they're experiencing the most change and growth, so trying to establish a schedule or routine now may be nearly impossible as their stomachs become larger, are able to hold more milk, etc.
The best advice our pediatrician gave us when we had our first child was to listen to your baby and let them dictate what they need these first few months.
Our son was a snacker from birth. He'd nurse about 5-10 minutes and was done. He's still a snacker at almost 4. It's a healthier way to eat, so we encourage it. Our daughter's the opposite.
Babies are accustomed to the movement of your walking, driving, etc. while in your womb, so for a few months, they're really most happy in swings, bouncy seats, car seats, etc. Motion is very comforting to them.
Swaddling has nothing to do with gassiness - gassiness is purely based upon how she's digesting your breast milk (and may be affected by what you're eating/drinking, medications you're on, etc). Gassiness may also be accumulating during the day, and she may need you or the nanny to help her relieve it by pressing on her tummy, holding her differently, giving supplements of Mylicon, etc.
Trust your instincts - they're amazingly powerful. If your pediatrician didn't give you a free copy of "Your Baby's First Year", I'd ask for one. It was my saving grace with our first child (never opened it with the second).
Good luck. Enjoy your daugther and spoil her as much as possible right now.
