Ok so I have time to write something in depth down.
Never write anything off. Advice from moms that have been there RECENTLY and have the same beliefs as you is invaluable. Still everyone does things different so what they may do you might not find the easiest.
I have 3 under 5 (until Feb) and I have done something different with all 3. The most drastic being Savannah. The ionly thing I have done with ALL three of them is make our own baby food.
I used to think babywearers were NUTS to wear past the first couple months but I was wrong. OH so wrong. Not all babies like it but of you have a baby that does OMG its soooooo much easier. You can get a NICE long term carrier at Babies R Us for 35 dollars (you can get it at some walmarts and targets too.) Its called the Infantino Sash. It is a tie carrier but it is NOT hard at ALL to do. I was scared to try a Mei Tei (what the name for the sash is called) with Morgan because of his heft but I went to a Babywearer meetup and I tried one with Savannah and I was HOOKED. I could wear her and Morgan at the same time and it was EASY to do alone. I went out and bought it that night and tried Morgan in it at home. Its now my go to carrier in the house because I have to do NOTHING to switch it between the two. I can post a video on how my teacher taught me to tie it (different then the instructions and ALOT more comfy). Savannah is a baby that HATES being put down and the carriers make life SOOOO much easier. Between shopping and everything I cant imagine doing it alone without the carriers.
Excuse me looking pissy LOL (this is not the carrier I talk about its a different MUCH more expensive one that I LOVE but the price is rather up there
)
Cloth diapers. If you can handle them they are AWESOME and I can help you find them cheaper (I paid 200 for 50). They can be daunting and overwhelming at first but it gets easier and better with time. If you plan to cloth diaper you will have to be on the look out for Cloth Diaper friendly clothes. Onesies need to be a size up for the most part (Gerber brand is a waste with cd's) and for little girls leggings and shirts or dresses are still CUTE, girly and work GREAT. Also for the house in the winter LEGWARMERS. You can get them on Ebay for $3 a pair..
Carseats Only use a used one if you KNOW the party you are getting it from. Not all carseats are created equal no matter WHAT any brand claims. They all go through the same tests by federal mandate but there are some that are tested BEYOND that. I would have a CPST help you install. Some will do it for free others charge a small fee because the certification requires CONSTANT education. Your fire department and/or police station usually does not have to take anywhere NEAR the educational classes as a CPST does much less stay up to date on the information. Jeremy learned as a firefighter on a ANCIENT carseat and learned nothing of Latch or anything. (I actually taught HIM how to put the seat in)
Also if you can borrow a swing and bouncer I would. Babies TEND to prefer one over the other or in my case neither.
HAVE back up plans for the things you WANT to do and do not think of them as preparing to fail. Have a couple bottles and a can of formula (save the reciepts and do not prep them). You want to have time to make your choice not rushing to the store at 2 AM trying to figure out what you want with a upset baby, no sleep and the stress.
Most of all be flexible. Babies have their own personalities and likes/dislikes. Things happen out of our control. As long as you take care of your baby you are NOT a failure. Even falling in love with your baby can take time it's not always this instant I'm in love feeling like you see in the movies.
ETA: If you MUST use baby detergent Purex smells like Johnsons baby wash instead of stinking like powder, also free and clear is cheaper and you get the same result just not the "baby" smell.
Also you do not NEED the expensive tubs or anything the best tub I have found is the basic tub with the sling, we also use our towels on the babies you can cover the head and they have towels when they are too big for the hoodeds. Bumper pads are advised against. I DID use them and never had issues but you can only use them a short time until you either need to take them off or use the mesh.
Learn how to swaddle. I know that sounds silly but with the swaddlers out on the market many moms do NOT know how to. If anyone wants I can take a video of me swaddling Savannah.
Moby blankets are $$ but they are AWESOME. You can get them at diaper.com
OH and lingere bag for socks. take them off the baby and put them STRAIGHT in there and wash and dry them in it.
Im sure I will think of more.
