P.G.
Baby needs closeness with mama. You are number one. And, no, you can't get too much accomplished with a newborn. Set your goals fairly low: I will get one load of wash done! whoo hoo!
I carried my little one in various carriers. A few pediatrician friends recommended using different ones so that baby's legs didn't grow according to the carrier and have walking/crawling issues. I used a sling (babies legs together or criss-crossed), a bjorn (babies legs out in front) and eventually the ergo (babies legs in a split). This is good physical positioning for the baby to be stretching in each different carrier before crawling/walking etc.
I have found the carriers to be amazing. I was able to get my work done, run a classroom of children, clean, and eat while carrying my little one. She was happy, I was happy. We didn't buy into all the big baby toys or seats, just three carriers.
Also, a little side note, the Native Americans used to (and many still do) attach their babies to cradle boards for the first YEAR of their lives and wear them around. These are very restrictive to movement and were thought to be detrimental to physical growth and movement. Therefore, a research study was formed. These Native American children crawl and walk and catch right up to where our American children are within a couple of months after being released from the board. Many surpass our American children due to the fact that our kids have so many 'handicaps' like the amount of walking toys and bouncy seats and toy distractions etc. Once more, their language skills are phenomenal, due to the fact that they listened, observed, and mimicked the language of their parents and family while being carried around for a whole year!
I found this to be true to my life. I carried my daughter for the first year in a carrier, she was put down here or there for tummy time, (which she hated!) to play with others, when she wanted to. She started talking at 7 months old, clearly. My pediatrician was shocked! By a year and 2 months, she said her first sentence which was also and observation ("mama, look! It's a bike.) Her language skills are incredible. She started counting things, not just reciting numbers, shortly after her first sentence. It may be many things, but I attribute much of it to her exposure and observation of language by being carried and not sat away from me, plus: no tv at all, telling stories, reading books, singing, and I talk to her all the time.
good luck with mamahood.
