I think bees are being way too harsh here. “Stay sane” to me is just a saying. “Well-behaved” baby is just how she worded it, nothing alarming. I read tons of posts and articles referring to babies as “easy baby” “angel baby”….there was even a baby book I read (eating, sleeping, being ftm practices) and it classified babies into categories and gave tips on how to approach each (I don’t remember all of them, but something along the lines of easy, sensitive, passionate, grumpy). I am a ftm to 6 mo old twins – and “well-behaved” to me meant “baby who is not colicky, not crying a lot, is generally content, doesn’t need to be constantly held, sleeps without much effort…etc.
And OP explained that super long outing was one time occurrence, usually her other trips are much shorter. There is nothing wrong wanting to get out of the house with the baby, some people are more introverted and love staying home in pjs cuddling, some are not, and need constant interaction, can’t sit at home for a day type – and just because one became a mother does not mean she is all of a sudden a different person who wants to stay home all day every day cooing at her baby. I had a c-section with twins, and I could not stand to stay home all day after less than a week – after that I was out and about and made it a point to get out almost every day (even though it was a hassle with 2 infants).
And newsflash – this age, babies are a little boring. They sleep almost every hour, eat, poop….there is not a lot of play and interaction yet. I can’t wait until I can do kids activities with the girls, but in the newborn stage I do things I like, want to do, and they come along for the ride. They would not know the difference if they are in a store with things to look at, or at a baby and me class (that a lot of times, baby sleeps through the whole thing anyways).
At 6 weeks, tummy time is still supposed to be relatively short, and she is giving her baby tummy time daily, holding her baby at home, plays, etc.
In other countries, the culture is not that mom stays with her baby at home 24/7 and does nothing but coos with the baby – parents continue lives as usual and baby comes along for all the adventures (while still being very well taken care of, fed, held, cuddled, loved, etc).
However, I do believe that for outings, a baby carrier would be a much better option than a travel system. You get to bond, baby gets used to your smell, warmth of your body, etc. And you can move faster than when having to push a stroller. Ha. I wish I could baby wear all the time, but with 2 it was more challenging so I always have to have a stroller with me. I wish I could throw it away, I hate that heavy, bulky, bus looking thing 😉
