I'm a first time mom so my first couple weeks may not mean much to a professional like you
My dd is almost eight weeks and I never believed all the mamas who told me that the crazy beginning (esp with breastfeeding) would be a blur. The first couple of weeks I was sad (really missed being pregnant for some reason) and didn't know what to do when my baby fussed. I thought all my experience with kids and babies would make me a magician but it didn't; I had never had a newborn of my own!
I also felt very isolated and claustrophobic in the house and tied down to near constant feedings. I hated to admit it but I missed my old life, snuggling with my husband, not feeling so incompetent...and I lived in fear that I would always feel this way. I would never have believed that I could so quickly turn into someone who loves being a mom and loves her baby more than anything in the world
Luckily I ran on pure adrenaline for awhile and didn't feel exhausted until the past couple of weeks. My mom did a lot for me during the day in the beginning and hubby fed once a night. We were both in survival mode and trying to find out what made the little one tick.
Another thing that made our life easier was swaddling. I kinda thought she hated swaddling, but we now do the five Ss (swaddling, shushing, swinging, sucking---now I forget the fifth!) religiously when she crabs and never have to deal with more than three or four minutes of screaming. We DIDN'T do that the first few weeks (even though I'd read Dr. Karp's book) but once we started it was life changing.
That's my first couple of weeks. Glad I got it under my belt so the next one isn't such a shock!!
