For instance, drive-thrus (can you make that plural?). I always considered drive-thru windows somewhat redundant in some cases and in others for the lazy. Don't think for a second that I didn't use them before baby (BB); However now I understand their importance and they are a downright necessity for a new mom. I find myself wishing there was a drive-thru version of every venue I frequent. Grocery shopping would be considerably easier if you could just go through a drive-thru. Somehow I managed to buy a house in the only neighborhood in the US that DOES NOT have a Starbucks with a drive-thru close by.
Mom Jeans

Fashion High Waisted
Another thing I never understood BB were high-waisted pants and I am not talking about fashionable high-waisted...I am talking about mom jeans. I thought they were a fashion faux pas that I would never repeat; However when you have gone from housing a 6-9 lb baby inside your body to all of a sudden giving birth you have a little extra belly going on. Now I am happy to report the belly goes down quite quickly but any "pinchiness" around the mid-section is not cute Post Baby (PB).
The other thing that I am discovering is the definition of "sleeping". I know you don't get a lot of sleep with a newborn but BB I was unable to function on less than 9 hours of sleep ( for prolonged periods of time). Now I am somehow able to form complete sentences, most of the time, on a mere 4 hours of sleep and that is a COMBINED 4 hours! The little miss has taken to sleeping in 2 hour intervals, meaning by the time I feed her and put her down I have less than 2 hours to sleep :) So sleep has taken on a whole new meaning. I used to call the sleep I get now a nap or cat nap.
I am sure there are more unexpected discoveries I will make as the weeks go by and when they happen I will update! Motherhood is quite an adventure and I feel incredibly blessed to be on it!
